pkg/rpcserver: move kernel test/data range checks from executor

We see some errors of the form:

SYZFAIL: coverage filter is full
pc=0x80007000c0008 regions=[0xffffffffbfffffff 0x243fffffff 0x143fffffff 0xc3fffffff] alloc=156

Executor shouldn't send non kernel addresses in signal,
but somehow it does. It can happen if the VM memory is corrupted,
or if the test program does something very nasty (e.g. discovers
the output region and writes to it).

It's not possible to reliably filter signal in the tested VM.
Move all of the filtering logic to the host.

Fixes #4942
