helpers: improve my_system function

Browse Source 
Instead of hardcoding the maximum number of arguments to the
my_system helper, pass a variable argument list.
The function is deliberately source-incompatible with the old
implementation (as opposed to a variant with a sentinel NULL
argument, which would be compatible) to find all users and to
make sure that new future users of this function are not
overlooked during merges with other branches.
