"deny file" -> Invalid mode

File tst/simple_tests/file/ok_bare_1.sd from the test suite doesn't parse correctly:

sarnold@hunt:~/trees/apparmor/parser$ cat tst/simple_tests/file/ok_bare_1.sd
#
#=Description bare file rule
#=EXRESULT PASS
#
/usr/bin/foo {
  deny file,
}
sarnold@hunt:~/trees/apparmor/parser$ ./apparmor_parser -Qd tst/simple_tests/file/ok_bare_1.sd
AppArmor parser error for tst/simple_tests/file/ok_bare_1.sd in tst/simple_tests/file/ok_bare_1.sd at line 6: Invalid mode, in deny rules 'x' must not be preceded by exec qualifier 'i', 'p', or 'u'

This is checkout at version 3338

This also exists in at least trusty's apparmor_parser too: 2.8.95~2430-0ubuntu5.3
