Fix alpine Makefile "panic" subst on MacOS

[kludev <kludev%gmail.com@localhost>]

Hi I made a fix to mail/alpine package wondering if anyone can help take
a look? Here's the Github PR (sorry I'm not sure if this is the proper
way to contribute patches).

Alternatively, here's the git diff:

    Fix alpine Makefile "panic" subst on MacOS

    The alpine's Makefile has source string subtitution for `panic(` to
    `Panic(`. However, both the file name search pattern and the replacement
    string search pattern is no longer complete, causing some
    `alpine_panic()` to still exist, while the definition has changed to
    `alpine_Panic()`.

    This change fixes that.
