Put libunicodenames back in same place
Opentype script tag for Malayalam v.2 is mlm2. The interface still shows incorrect mly2. This complements b13ee269d4eafb99e61fa44ed5325b8de7398b4c which fixed certain cases.

fontview.c #ifdef cuts-out too much inside if (done) statements.

My error. This Corrects error in applying #ifdef conditional compilation
when no library is found or if ./configure. --without-libuni___ specified.
Popups were blank when no library present, and the elseif was not followed
because endif was applied to exclude entire "if (uni!=-1)" branch.
Problem appeared in Mac binary version with this example:
