Changes for apptainer:

• Update apptainer to version v1.5.1

• Work around segmentation fault sometimes seen while mksquashfs under proot is creating a SIF file.
• Update bundled PRoot to version 5.4.0-rootless.3 in order to fix a problem where SIF files could be corrupted when mksquashfs died with a signal. The proot command was not passing back an error exit code.
• Updated bundled squashfuse_ll to version 0.6.2 in order to fix a crash sometimes seen with apptainer in unprivileged docker.
• Update bundled fuse2fs to version 1.47.4 instead of patching the bugs in 1.47.3.
• Fix a crash that happened when /etc/resolv.conf was a symlink while building from a definition file using the localimage bootstrap.
• Support hosts that have an /etc/resolv.conf symlink pointing to ../run in addition to /run.
• Change the download-dependencies script to skip downloading the PRoot source code on architectures that it is known to not support (that is: ppc*, s390*, and riscv*). In those situations Apptainer will skip trying to compile and run proot. As a result original owners and groups of files will not be preserved in SIF images built by unprivileged users, as was the case for all architectures prior to 1.5.0.
• Fix panic encountered during progress bar update while pulling image.
• Fix fakeroot overwriting root's username in /etc/passwd with the host user's name, a regression introduced in v1.5.0.
• Add nonested flag for --mount specifications to prevent individual bind mounts from being passed to nested containers via APPTAINER_BIND.
