package/qt5base: drop remnants patches from previous version

When the bump to 5.11.2 was applied, master gained a new patch for 5.11.1
in-between the bump submission and the moment it was applied. That patch
still lingers around now.

Since that patch has been applied upstream (it is detected as a revert
when applied to 5.11.2), we simply drop it.
