CKM: Gdbbacktrace tries to become root

[Problem] When gdbbacktrace is executed as ordinary user it has no permissions
to attach with gdb or unlink output file.
[Solution] Add seteuid/gid(0) in the beginning of gdbbacktrace.

[Verification] Run any failing test that uses ScopedAccessProvider with uid/gid
There should be no "gdbbacktrace() failed: No backtrace information"
