rename hash.? to idu-hash.? to avoid conflict with gnulib's hash.h

Now that gnulib's exclude module uses gnulib's hash module,
which includes a hash.h file, idutils' use of a hash.h file conflicted.
Rename the one here in idutils:
* libidu/idu-hash.c: Rename from hash.c.
* libidu/idu-hash.h: Rename from hash.h.
* libidu/idfile.h: Reflect renaming.
* libidu/idread.c: Likewise.
* libidu/idwrite.c: Likewise.
* src/mkid.c: Likewise.
* libidu/Makefile.am: Likewise.
