games-emulation/snes9x: add 1.61

Various changes, but for some notable ones:
- IUSE=gtk->gui, now uses gtkmm
- RESTRICT=test, has no tests but fails if -gui/-gtk (bug #737044)
- clean libretro objects to fix USE="netplay libretro" (bug #791475)
- respect flags for libretro, also don't use CXXFLAGS for CFLAGS
- install libretro core in libretro/ like libretro-snes9x
- tentatively remove noexecstack, not seeing QA notices
- remove html docs, they are not relevant for users

This bundles glslang/spriv-cross but upstream is concerned about API
and seems likely this will break if unbundled, leaving alone for now.

bug #766782 was caused by CFLAGS = $(CXXFLAGS) without := leading
to -fno-rtti being used for CC and seemingly being refusedby distcc.
1.61 corrected this.
