Merge #1730

1730: Ignore doctests for unexported macros r=asomers a=zombiepigdragon

Due to rust-lang/rust#97030, cargo test will fail to doctest macros unless they are exported, breaking the examples for `libc_bitflags!` and `libc_enum!`.

Adds `ignore` to the examples for these macros to stop tests from failing.

`cargo test` already fails on cargo 1.62.0-beta.2, and the above issue makes it seem unlikely that this will be changed on the Rust side. If rust-lang/rust#96630 *does* get reverted, this PR can be closed/unmerged, although the test wasn't running beforehand, and it might be worth making this explicit regardless.
