Subject: [PATCH] src/mmap_hook.cc: Fix build for 32bit machine

Fixed build error on 32bit machine:

../git/src/mmap_hook.cc:309:31: error: static assertion failed
 309 | static_assert(sizeof(int32_t) == sizeof(off_t), "");

This is because oe's off_t is 64bit on both 32 and 64bit system, which is the
default value of glibc, so the assertion would be failed on 32bit system, and
remove mmap() and mmap64() to fix the redefined error.

Upstream-Status: Inappropriate [OE-Specific]
