configure: improve warning when all qpa plugins disabled with features.gui 

The mentioned README file has never been very trustworthy and
after 863c688749 it has become
very minimal - it doesn't contain anything that is not already
present in "configure --help" and enforced by the configure
process. Furthermore, the warning was XCB specific, but Qt
supports also other QPA plugins on linux.
