Clang 16 introduced a warning about single bit bitfields in structs,
which is triggered by various declarations in libarchive:

Signed one-bit bitfields can only have values -1 and 0, but the intent
here is to use the fields as booleans, so make them unsigned.
This has also been sent upstream.

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.

libarchive: Apply upstream commit a1b7bf8013fb7a11a486794247daae592db6f5ae
This fixes the failing test_read_append_filter_wrong_program test in CI
which has been failing since 01-Dec-2020.
Commit message from a1b7bf8013
Silence stderr in test_read_append_filter_program
When the FreeBSD testsuite runs the libarchive tests it checks that stderr
is empty. Since #1382 this is no longer the case. This change restores
the behaviour of silencing bunzip2 stderr but doesn't bring back the
output text check.
