qmake: prune dysfunct libtool reader from QMakeMetaInfo

in principle, it would be good to be able to read libtool .la files as
an alternative to our "proprietary" .prl files. however, this code was
disabled 15 years ago, three months after being written and never
released, and apparently no-one was missing it.
