Handle top __syscall_cancel frames when getting stack traces

Since glibc 2.41 there are extra frames inserted before doing a
syscall to support proper thread cancellation.  This breaks various
suppressions and regtests involving checking syscall arguments.

Solve this by removing those extra frames from the top of the call
stack when we are processing a linux system call.
