jobs.yaml: Fix suite for LTP syscalls-ipc suite

The LTP syscalls-ipc job actually specifies the syscalls suite which is
a *much* larger suite that doesn't finish in the allocated time, causing
constant timeouts for every job that is scheduled.  Use the expected
suite name to schedule the much smaller syscalls-ipc suite.
