testlimits: optionally accept '-timeout' input

Browse Source 
Fixes: #1032

The testlimits tests can use a lot of system resources, and thus they
may fail when run on systems under heavy load, given that the default
parsing timeout is set to two seconds. Retain this default value, but
make the timeout length configurable with a new '-timeout' flag.
