patch: show lower-ed translated message correctly

Before this patch, patch.filterpatch() shows meaningless translation
of help message for chunk selection in some encoding.

It applies str.lower() instead of encoding.lower(str) on translated
message, but some encoding uses 0x41(A) - 0x5a(Z) as the second or
later byte of multi-byte character (for example, ja_JP.cp932), and
str.lower() causes unexpected result.

To show lower-ed translated message correctly, this patch replaces
str.lower() by encoding.lower(str).
