'Determines if the given file at :param:`path` is a software package
This check will be used to determine if :method:`load_package_info`
will be called for file at :param:`path`. This method should be
implemented by classes inheriting from :class:`DistroPkgInfoLoader` and
could be as simple as checking for a file suffix.
:param path: path to the software package file
:type path: str
:return: either True if the file is a valid software package or False
otherwise
:rtype: bool'
