Create lock file in config folder instead of temp folder

Browse source 
Some linux distros seem to alter TMPDIR environment variable and
therefore hamper qbt ability to find the lock files. So use config
folder instead of TMPDIR folder to create/locate the lock files.
Note that this change will also make qbt become one instance per-user
instead of one instance per-system.

Closes #15646.
