Ignore LC_CTYPE if set to "UTF-8"
LC_CTYPE is set to "UTF-8" on some macOS systems, which is
POSIX-compliant in a strict sense, but breaks the usual assumption
that a locale name has the form "ll_LL.encoding".

Previously, this would cause the warning
Fontconfig warning: ignoring UTF-8: not a valid region tag
Now, we just skip this variable if set to "UTF-8", since that value
doesn't give any language information, and move on to try LANG.
