name-parser: Fix SIL replacements

[why]
If the font name is changed in a way where it now ends in a blank (for
example because 'Name Momo' got 'Momo' dropped: 'Name '), that blank is
not removed immediately.
Well, it is later on, but anyhow.
This can only happen on malformed SIL entries. But we want to have a
correct replacement anyhow.

[how]
Remove trailing whitespace after replacements.
