sepolicy: ignore comments and empty lines in file_contexts.subs_dist

In refpolicy, file_contexts.subs_dist begins with comments:

    # This file can is used to configure base path aliases as in:
    #
    # /aliased_path /original_path_as_configured_in_file_contexts
    #

The first line gets parsed in read_file_equiv even though it is not a
valid path substitution and the second line triggers an exception when
accessing f[1]:

    IndexError: list index out of range

Parse substitutions only for lines which are not comment.
