kde5 fpicker: Drop 'getFiles' and 'getSelectedFiles'

... and related signals/slots.

Those from the Qt5FilePicker base class do the same thing,
except for one 'SolarMutexReleaser' that was commented out
in 'KDE5FilePicker::getFiles' for no apparent reason since
that line was added in commit 8fb0881a.

Take over the slightly nicer syntax for the range-based for loop
from 'KDE5FilePicker::getSelectedFiles' to
'Qt5FilePicker::getSelectedFiles'.
