generatelocales: fix 'cut' invocation

'cut' needs to be invoked with the -s option to make sure it doesn't
print anything when the delimiter isn't found. This is particularly
important for the charmap detection, because UTF-8 is appended if
the charmap is empty. But without -s, it will never be empty.
