alpine: fix subst on macOS

The alpine's Makefile has source string substitution 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().

From kflu via github.

Closes #113
