tst_QMessageLogger: disable Android once and for all

The messages said "This test crashes on Android" bu tit appears the
problem is not a crash, but that the executable can't be executed. The
file appears to be present and yet execve() is producing ENOENT (No such
file or directory). That probably means it's the interpreter stored in
the ELF header's dynamic section that is not found.

Fixing that is SEP[1].
