meta: Don't _mesa_set_enable() invalid targets in ES 1.

Browse Source 
GL_TEXTURE_1D, GL_TEXTURE_3D, GL_TEXTURE_RECTANGLE, and
GL_TEXTURE_GEN_S/T/R/Q don't exist in ES 1 contexts, so any meta ops
that used _mesa_meta_begin with MESA_META_TEXTURE would trigger GL
errors.  One such operation is _mesa_meta_Clear().

On ES 1, we want to disable GL_TEXTURE_GEN_STR_OES instead.

Fixes the ES1 conformance test miplin.c, which was regressed by commit
08be1d288f216232d3974f5997b266a8dd720928.

NOTE: This is a candidate for the 9.0 branch.

v2: Also blacklist GL_TEXTURE_3D, per Brian's comment.
v3: Disable GL_TEXTURE_GEN_STR_OES, per Ian's comment.
