lang/jpm: Update to 1.2.0

[dave_freedave.net]

Summary

Technically all that was needed was bumping the DISTVERSION, removing PORTREVISION, running make makesum, and adding a new file to pkg-plist.

But I wanted to have a way to quickly test, and both portlint -A and portclippy --strict Makefile had a few nits so I went ahead and addressed them.

Test Plan

I need an updated jpm(1) to build the latest spork (a popular janet library). While spork can be built without jpm(1) it does make for an easy test: verify jpm install works for spork which I have done.

Also added a do-test target and verified make test works.

Just ran poudriere testport -j FreeBSD15 -p local lang/jpm and could probably use NO_ARCH=yes like D54667.

===>   Building jpm-1.2.0
pkg-static: DEVELOPER_MODE: Notice: arch "FreeBSD:15:amd64" -- no architecture specific files found:
**** could this package use a wildcard architecture?

add NO_ARCH=yes

This looks wrong. The file always contains "/usr/local" while LOCALBASE may be set to something else. In this case sed would replace nothing.

Same here. If something always creates "/usr/local/..." then using the LOCALBASE variable is wrong.

[dave_freedave.net]

For reasons @arrowd pointed out changing LOCALBASE back to /usr/local. I incorrectly trusted portlint on those.

Also just removed from do-test to match do-install target.
