libarchive: cherry-pick bugfix from vendor
Vendor commit message (ede459d2e):
archive_write_disk_posix: fix writing fflags broken in 8a1bd5c The fixup list was erroneously assumed to be directories only. Only in the case of critical file flags modification (e.g. SF_IMMUTABLE on BSD systems), other file types (e.g. regular files or symbolic links) may be added to the fixup list. We still need to verify that we are writing to the correct file type, so compare the archive entry file type with the file type of the file to be modified.
Fixes vendor issue #1617:
Immutable flag no longer preserved during tar extraction on FreeBSD
