libdpkg: Move compression level max bound check from dpkg-deb

The compression level max bound check is specific to each compressor,
and we cannot simply use a single max bound for every compressor. Move
the check into the compressor_check_params() function where we can check
whether it is coherent with the compressor requested.

The dpkg_options_parse_arg_int() already makes sure we get a sanitized
value that is 0 or larger but not larger than INT_MAX.
