dev-util/shader-slang: (really) avoid collision with sys-libs/slang

wrt path name, not packaged in many distros (yet), but I've seen some
use /usr/include/shader-slang rather than /slang, let's go with this
given it's more specific. Same reason avoided naming the package
"slang" despite upstream is "slang-${PV}".

Believe(?) consumers should not ever have a reason to specify this
path themselves, both shader-compiler.pc and the cmake target add
the include dir -- so the path ultimately should not matter much.

Closes: https://bugs.gentoo.org/980471
