libxbps: use OpenSSL SHA256, 5x faster xbps_get_file_hash() implementation.

Browse Source 
* libxbps: improved xbps_get_file_hash() to mmap(2) rather than read(2)
  the file we have to process. With mmap'ed files the hash can be
  processed 5x faster than before, or even more in some cases.

* libxbps: switch to OpenSSL SHA256 implementation and remove the one
  previously used. It's faster and OpenSSL is required for libfetch so
  there is not point in using it.
