FindQt3: Restore missing lib and bin path suffixes

Restore path suffixes incorrectly removed by commit a62d50ec56 (Modules:
Replace coded PATHS with PATH_SUFFIXES, 2017-11-20, v3.11.0-rc1~293^2).
Hints do not participate in the usual bin/lib subdirectory search that
`<PackangeName>_ROOT` or `CMAKE_PREFIX_PATH` exhibit.

Fixes: #19185
