[LTP] [PATCH v2] Make crash02 verbose in standard runfile

[Martin Doucha]

Verbose output from crash02 will be useful for actually reporting bugs
triggered by the test. With default verbosity level, it's difficult to figure
out which syscall arguments crashed the system even if you know the random seed
and can easily re-run `crash02 -xv 2` on a system that uses the same rand()
implementation.

Changes in v2: Bring -x implementation in line with usage description.
