gnu: icecat: Enable Stylo CSS engine.

Browse source 
* gnu/packages/gnuzilla.scm (icecat)[native-inputs]: Add 'llvm-3.9.1' and
'clang-3.9.1'.
[arguments]: In the configure-flags, use quasiquote, remove "--disable-stylo",
and add "--with-clang-path=..." and "--with-libclang-path=...".
Add 'augment-CPLUS_INCLUDE_PATH' phase.  In the custom 'configure' phase,
set the CC environment variable to "gcc".
