[PATCH v2] am: invoke perl's strftime in C locale

["Dmitry V. Levin" <ldv@altlinux.org>]

This fixes "hg" patch format support for locales other than C and en_*.
Before the change, git-am was making "Date:" line from hg changeset
metadata according to the current locale, and this line was rejected
later with "invalid date format" diagnostics because localized date
strings are not supported.
