android,autotools,i965: Fix location of float64_glsl.h

Android.mk and autotools disagree about where generated files should
go, which wasn't a problem until we wanted to build a dist
tarball. This corrects the problem by changing the output and include
paths to be the same on android and autotools (meson already has the
correct include path).

Fixes: 7d7b30835cfb9eb89beca9fb8593d0954f79b84d
       ("automake: Fix path to generated source")
