shm.c: Replace stat64/fstat64/ftruncate64mmap64 with normal functions

These functions were needed when _FILE_OFFSET_BITS was not 64, using
AC_SYS_LARGEFILE will detect it correctly and make the normal variants
of these functions behave same as their *64 counterparts.

Subject: [PATCH] shm.c: Replace stat64/fstat64/ftruncate64mmap64 with normal
functions
These functions were needed when _FILE_OFFSET_BITS was not 64, using
AC_SYS_LARGEFILE will detect it correctly and make the normal variants
of these functions behave same as their *64 counterparts.
