Remove support for loadable gconv transliteration modules.
The support for transliteration modules has been non-functional for
over a decade, and the removal is prompted by security defects. The
normal gconv conversion modules are still supported. Transliteration
with //TRANSLIT is still possible, and the //IGNORE specifier
continues to be supported. (CVE-2014-5119)
Based on upstream commits a1a6a401ab0a3c9f15fb7eaebbdcee24192254e8
and f9df71e895d3552d557e783fdb9d133328195645
