Update ipxe version to December 2023

This is yet another tentative to make ipxe more close to the
current version and include some improvements and bug fixes.

We point the ipxe commit hash to [1] from December 2023, so
roughly a year of changes is included.
To see the complete list of changes run:
`git log --pretty=oneline 714753..119c41`
from a local clone of the ipxe repository.

In general the changes included between the old hash and
and the current chosen hash improve compatibility
with recent gcc and build libraries, while fixing
numerous bugs.

This is a follow-up to 7c34282
