egl: stop claiming support for pbuffer + msaa
This fixes a crash in egl-create-msaa-pbuffer-surface Piglit test
and same crash in many dEQP EGL tests.
I also found that some Qt example did a workaround because of this
crash: https://bugreports.qt.io/browse/QTBUG-47509
v2: Ian pointed out that v1 removed support for all multisample
configs, including window ones. This one removes pbuffer bit
when adding configs, now only pbuffer+msaa gets rejected and
window+msaa continues to work. Fixed also comment (Emil)
