libarchive/get_header_ar.c: fix extraction of archives from binutils in deterministic mode
GNU binutils in deterministic mode (ar rD or built with
--enable-deterministic-archives) hard codes file mode to 0644 (NOT 0100644)
since https://github.com/bminor/binutils-gdb/commit/36e4dce69dd2
This confuses busybox ar x (data_extract_all):
touch a; ar rD a.ar a
ar: creating a.ar
busybox ar x a.ar
ar: unrecognized file type
hexdump -C a.ar

As a workaround, force the mode bits to S_IFREG, as nothing else makes sense
for ar.
