browser: sort names that differ only in case with uppercase first 

This is the opposite of what 'ls' does in a UTF-8 locale, but nano
has never followed the collating rules of Unicode (uppercase after
lowercase, ignoring punctuation, and so on) -- it would be strange
to change that now.

Until now, nano left such equivalent names unsorted, in a seemingly
random order.

This fixes https://savannah.gnu.org/bugs/?59059.

Bug existed since before version 2.0.6.
