The two functions is_tcf_skbedit_mark() and is_tcf_skbedit_ptype() have a
very similar structure. A follow-up patch will add one more such function.
Instead of more cut'n'pasting, extract a helper function that checks
whether a TC action is an skbedit with the required flag. Convert the two
existing functions into thin wrappers around the helper.
