lang/janet: Update to 1.42.0

[dave_freedave.net]

Summary

I noticed on Janet zulip that they added filewatch via kqueue(2) to janet when creating this version.

I thought (but was wrong) that we had inotify(2) on all supported FreeBSD versions but that wont be true until next year. Anyway you get better file watch support for all the reasons given here.

But that requires patching here instead of upstream. sigh.

Test Plan

Manually run testport with -i and check that for stable/14 it does not have inotify_init1 symbol and that it does have it for stable/15:

poudriere testport -j FreeBSD14 -p local -i lang/janet
nm /wrkdirs/usr/ports/lang/janet/work/janet-1.42.0/_build/libjanet.so | grep inotify_init1

poudriere testport -j FreeBSD14 -p local -i lang/janet
nm /wrkdirs/usr/ports/lang/janet/work/janet-1.42.0/_build/libjanet.so | grep inotify_init1
                 U inotify_init1

logs for stable/14:

fbsd14-janet-1.42.0.log41 KBDownload

logs for stable/15:

fbsd15-janet-1.42.0.log40 KBDownload

And of course make test passes for both.

have to use bsd.port.pre.mk and bsd.port.post.mk or it doesn't have INOTIFY_PORT set.
