qt5virtualkeyboard: fix patch applied to 2.0 version

The patch 0001-remove-weird-install-path-for-example.patch using
patch: does not apply properly and needs to be fixed.

The patch was backported from 5.7 [1] with path adaptation in commit
(cb97d947 qt5virtualkeyboard: allow to build with qt5.6), but the
submitted patch did not reflect that said adaptation.

Apply the said patch adaptation (i.e. add missing basic subdirectory) to
apply properly the patch.

Fixes:
