filter_gdb patch to handle "result = SYSCALL_CANCEL" pattern
SUMMARY
mcinfcallWSRU, nlcontrolc and nlvgdbsigqueue tests failed in aarch64 in rhel-8.
The cause is the same in the three tests, an extra line in the output which is
not expected. Using nlcontrolc diff output as example:

Following the same approach as seen in commit 3eba47604df8, adding a new
pattern to gdbserver_tests/filter_gdb.in should suffice. After rerunning with
it, the tests are passing. I'm attaching a proposed patch.
