Fix gen_wc8bit support for finding a UTF8 locale on host.
gen_wc8bit was previously patched to support UTF8 locales other than the default en_US.UTF-8 by patch id 0e14b8f425c562749d3821a42414b1ce6b3b0923. This was incomplete in its implementation and still failed where item(s) in the list returned by 'locale -a' already had 'UTF8' appended to the name. This patch rectifies this situation, plus adds an extra fix to avoid trimming '\n' from an empty line which could cause a segfault.
