[PATCH] gitk: Remove mc parameter from proc show_error

[Alex Henrie <alexhenrie24@gmail.com>]

This is a better fix for 8d849957d81fc0480a52570d66cc3c2a688ecb1b.

All that was required to fix the original issue was to remove the extra
mc call, i.e. change [mc "Sorry, gitk cannot run..."] to simply
"Sorry, gitk cannot run..." Changing the signature of proc show_error
was unnecessary and introduced two new bugs: It made "OK" untranslatable
and "mc" translatable when the opposite should be true.

This new fix makes the string "OK" translatable and the string "mc" not
translatable, while leaving the string "Sorry, gitk cannot run..." not
translatable. It will take effect the next time `make update-po` is run.
