Enforce strict mode of jsmn.

[stoeckmann]

If no strict mode of jsmn is enforced, then the correct amount of
json elements would have to be checked to avoid segmentation faults
on malformed state files:

$ echo '{ "focusedMonitorId" }' > malformed-state
$ bspwm -s malformed-state
Segmentation fault
$ _

This alone won't fix the issue, because jsmn itself has a bug. See: zserge/jsmn#158

But after a merge of a new jsmn version this will fix the bspwm side of the issue.
