Jim Warner b9723148a2 library: eliminate insidious 'LIBPROC_HIDE_KERNEL' bug 
When support for the 'LIBPROC_HIDE_KERNEL' environment
variable was introduced, a deficiency was present that
allowed any rejected proc_t (i.e. a kworker thread) to
preserve the strdup'd 'cmd' value. That residual value
would prevent stat2proc or status2proc from updating a
cmd field with the proper program name for some tasks.

This patch just ensures a proc_t is freshened whenever
it has been rejected due to an active PT->hide_kernel.

[ again thanks to Björn for initiating the extension ]
