udev-rules: move udev_check_rule_line() invocation

Move udev_check_rule_line() invocation from udev_rule_file_get_issues()
to udev_rules_parse_file(), invoke udev_check_rule_line() only when
udev_rules_parse_file() is called by udevadm verify.

Subsequent commits are going to perform more checks invoked from
udev_rules_parse_file().
