[Mesa-dev] [PATCH] Revert "st/mesa: expose 0 shader binary formats for compat profiles for Qt"

[Timothy Arceri]

This reverts commit 55376cb31e2f495a4d872b4ffce2135c3365b873.

It's been over a year and both QT 5.9.5 and 5.11.0 contained a fix for the
original issue. It seems i965 only ever applied this workaround to the
18.0 branch.
