We don't need to apply QDir::absolutePath() on the diretory that
QLibraryInfo::path() returns, because that is already an absolute path
(and if it weren't, it wouldn't make a difference anyway). That means we
are only doing path concatenation here. For code this low-level, it's
better to stick to QString.
This commit also rejiggles the string variables so we avoid one of the
memory allocations when calling QStandardPaths.
