Require GL_EXT_sRGB_write_control for GL_FRAMEBUFFER_SRGB enable/disable

This test required GL_EXT_sRGB_write_control or ES 3.2.  But glEnable
and glDisable of GL_FRAMEBUFFER_SRGB requires the extension - ES 3.2
doesn't provide that functionality.  ES 3.2 implementations without the
extension would fail.  Now they report NotSupported.

Affects:
dEQP-GLES31.functional.fbo.srgb_write_control.framebuffer_srgb_enabled

Components: AOSP
