LOG: [libc][errno] Remove unnecessary include (#92063)

Since https://github.com/llvm/llvm-project/pull/91150, a proxy header
for the errno macros is available and gets included in `libc_errno.h`
since then.

As `libc_errno.cpp` includes `libc_errno.h`, which already includes the
proxy header `hdr/errno_macros.h`, there's no need to include it in
`libc_errno.cpp` if we are in overlay mode, because the proxy header
takes care to either include our header from libc/include/ (fullbuild)
or the corresponding underlying system header (overlay).

Added: 
    

Modified: 
    libc/src/errno/libc_errno.cpp

Removed:
