powerpc/crc: drop "glue" from filenames

The use of the term "glue" in filenames is a Crypto API-ism that rarely
shows up elsewhere in lib/ or arch/*/lib/.  I think adopting it there
was a mistake.  The library just uses standard functions, so the amount
of code that could be considered "glue" is quite small.  And while often
the C functions just wrap the assembly functions, there are also cases
like crc32c_arch() in arch/x86/lib/crc32-glue.c that blur the line by
in-lining the actual implementation into the C function.  That's not
"glue code", but rather the actual code.

Therefore, let's drop "glue" from the filenames and instead use e.g.
crc32.c instead of crc32-glue.c.
