Revert "skslc now uses standard Skia caps"

This reverts commit 8af38a96475ac5ce83b20c16d9cf82bf1006b8c4.

Reason for revert: Breaking compile bots, e.g. from https://uberchromegw.corp.google.com/i/client.skia.compile/builders/Build-Ubuntu-GCC-x86_64-Debug-NoGPU/builds/10029/steps/compile_skia%20on%20Ubuntu/logs/stdio :

In function `sk_make_sp<GrGLSLCaps, GrContextOptions>'
undefined reference to `GrGLSLCaps::GrGLSLCaps(GrContextOptions const&)

In function `_Z10sk_make_spI10GrGLSLCapsI16GrContextOptionsEE5sk_spIT_EDpOT0_':
undefined reference to `GrGLSLCaps::GrGLSLCaps(GrContextOptions const&)
