input-verify: add puppet verifier for puppetManifest input

Units/parser-puppetManifest.r/puppet-append.d/verifier is very special.

About puppet-append.d/verifier, the puppet verifier reports this input as
"invalid" because `+=' operator is obsoleted in puppet5.
@ahakanbaba in universal-ctags#1909 reported and proposed a fix for this already.
However, @masatake kept this as is for following reasons:

  - valid in puppet4,
  - testing KNOWN-INVALIDATION special verifier, and
  - testing '#' comment in a verifier file.
