libarchive: make single bit bitfields unsigned to avoid clang 16 warning
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.
