integritysetup: convert verbs to VERB macros

Place VERB() declarations above each dispatch function and use
verbs_get_help_table() in help() so the command listing stays in sync.
run() switches to dispatch_verb_with_args(); the argv_looks_like_help()
shortcut is preserved since this is an internal tool with no proper
option parsing.
