wm4 eb33556cbf egl_helpers: change minimum framebuffer size to 8 bit per component ...

This is for working around bugs in certain Android devices. At least one
device fails to sort EGLConfigs by size, so eglChooseConfig() ends up
choosing a config with 5/6/5 bits per r/g/b component. The other
attributes in the affected EGLConfigs did not look like they should
affect the sorting process as specified by the EGL 1.4 standard.

The device was reported as:

Sony Xperia Z3 Tablet Compact
Firmware 6.0.1 build number 23.5.A.1.291
GL_VERSION='OpenGL ES 3.0 V@140.0 AU@ (GIT@I741a3d36ca)'
GL_VENDOR='Qualcomm'
GL_RENDERER='Adreno (TM) 330'

Other Qualcom/Adreno devices have been reported as unaffected by this
(including some with same GL_RENDERER string).

"Fix" this by always requiring at least 8 bit. This means it would fail
on devices which cannot provide this. We're fine with this.
