Fini Jastrow 129e114ddf gotta-patch-em-all: Reactivate parallel processing ...

[why]
The messages from parallel font-patcher runs can be very confusing, so
it has been disabled some time ago (without a comment in that commit?!).

However, if someone wants to repatch multiple fonts on a local machine
it might be beneficial to run more than one process to have work on all
cores.

[how]
Add option to select multiple processes in parallel.
Limit the amout to 8, which might be a good value for typical end-user
machines with 4 cores and 8 threads.

Patching Cascadia Code (12 fonts) took these times on my machine:
  1 job:  21m 55s
  4 jobs:  6m 24s
  8 jobs:  5m 14s  (this runs 8 and then the remaining 4)
 16 jobs:  4m 48s  (this runs 12 in parallel)

Adding a proper `-j` that takes a numeric argument is rather too much
work for my taste, so we stick with 8 for now.
