feat: add support to x64 systems using musl

[samyuh]

Problem

When importing a data source of a file that was previously compressed using the snappy compression algorithm, the compression fails with the following exception:

Error loading shared library ld-linux-x86-64.so.2: No such file or directory.

This problem occurs since the dockerimage does not containg the ld-linux-x86-64.so.2 lib, which is from glibc. Alpine images use musl making this incompatible.

Having this dependency being linked dynamically can mess things up. Ideally, we would like to have snappy being compiled against a MUSL image.

Snappy removed pure-java mode 1.1.9.0 (https://github.com/xerial/snappy-java/pull/381/files), which could be used to run snappy in non-supported systems with the use of one flag. We could force an older version but it was removed due to some problems (such as data corruption) and older versions than 1.1.9.0 contain critical CVEs (https://mvnrepository.com/artifact/org.xerial.snappy/snappy-java).

Workaround

Alpine images also have some packages that allow us to run binaries precompiled against glibc libraries (they don't allow us to compile against it), such as gcompat. In our case, libc6-compat provides /lib64/ld-linux-x86-64.so.2 compatible lib. Turns out that /lib64/ld-linux-x86-64.so.2 is a symlink to /lib/libc.musl-x86_64.so.1. Adding a /lib/ld-linux-x86-64.so.2 linked to /lib/ld-musl-x86_64.so.1 solves the issue since that is the place snappy is searching for the dependency.

This is the same solution employed by https://stackoverflow.com/a/55568352.

Fix

The library now includes native binaries compiled specifically for musl environments, eliminating the need for workarounds like installing gcompat or libc6-compat packages in Alpine containers.

This improvement means:

• Direct compatibility with Alpine Linux
• No need for additional compatibility packages
• Better performance by using native musl binaries instead of compatibility layers
• Simplified deployment in Alpine-based containers

Closes #616
Closes #239

Hey @xerial! This is a pull request that gives compatibility with systems using musl. Can you please take a look at this? Thanks!

@samyuh It seems building a native library for Alipine is failing on CI. https://github.com/xerial/snappy-java/actions/runs/12839320244/job/36630155639?pr=632

Hey @xerial thanks for the feedback! I will try to make time to look into this later today :)

Pipelines should pass now, I just renamed one file and forgot to change it on Makefile

Hey @xerial
Anything else missing? (feel free to add any new commit if you want btw)
Thanks :)
