driver: On linux hosts disable ASLR during -freport-bug [PR119727]

Andi had a useful comment that even with the PR119727 workaround to
ignore differences in libbacktrace printed addresses, it is still better
to turn off ASLR when easily possible, e.g. in case some address leaks
in somewhere in the ICE message elsewhere, or to verify the ICE doesn't
depend on a particular library/binary load addresses.

The following patch adds a configure check and uses personality syscall
to turn off randomization for further -freport-bug subprocesses.
