<sys/_pv_entry>: Add a fallback for __LONG_WIDTH__ for older compilers.
clang only includes a __LONG_WIDTH__ builtin in clang 14 and later.

This was the smallest change to fix CI breakage. However, we may want to do

<sys/cdefs.h>, or we could change sys/_pv_entry.h to use the expanded form
always (or pick a different spelling?)
