Ilpo Järvinen f8a0c90baa selftests/resctrl: Ensure the benchmark commands fits to its array 
[ Upstream commit 4a28c7665c2a1ac0400864eabb0c641e135f61aa ]

Benchmark command is copied into an array in the stack. The array is
BENCHMARK_ARGS items long but the command line could try to provide a
longer command. Argument size is also fixed by BENCHMARK_ARG_SIZE (63
bytes of space after fitting the terminating \0 character) and user
could have inputted argument longer than that.

Return error in case the benchmark command does not fit to the space
allocated for it.

Fixes: ecdbb911f22d ("selftests/resctrl: Add MBM test")
