Add a function to remove previously-added abrt handler functions.
Now that a symmetric pair of add/remove functions exists we can also
balance the SIGABRT handler installation. The signal handler was
installed each time qtest_add_abrt_handler() was called. Now it is
installed when the abrt handler list becomes non-empty and removed again
when the list becomes empty.
The qtest_remove_abrt_handler() function will be used by
vhost-user-blk-test.
