Remove the definition of difftime

The build is broken after:
https://android-review.googlesource.com/c/toolchain/mingw/+/1350713

This is because difftime is defined as static __inline in the header file. We don't need a separate definition in .c file.

difftime.c is removed upstream in:
https://sourceforge.net/p/mingw-w64/mingw-w64/ci/19b6d96eb45ef1314e276f4ea6c3f2e0d7910120/
But this change is too big to cherrypick.
