functionObjects::/systemCall: Added optional parallel switch to execute on all processors

Browse Source 
When the parallel switch is set false (the default), the system call is executed
only on the master processor, if true it is executed on all processors.

Patch contributed by Stanislau Stasheuski, Aalto University.
