commit, tag: parse --trailer with OPT_STRVEC

Now that amend_file_with_trailers() expects raw trailer lines, do not
store argv-style "--trailer=<trailer>" strings in git commit and git
tag.

Parse --trailer using OPT_STRVEC so trailer_args contains only the
trailer value, and drop the temporary prefix stripping in
amend_file_with_trailers().
