backends: Include unistd.h to fix compilation on musl

Browse Source 
Musl doesn't seem to include this by default so explicitly including it
should fix compilation on Musl.

Tested with Clang 16/17 and GCC 14.

Error:
src/backends/meta-fd-source.c:70:3: error: call to undeclared function 'close'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
  close (fd_source->poll_fd.fd);
  ^
