  [compiler-rt][lsan] Add backup AArch64 register for use_registers test

On Ubuntu Focal x13 is used by something in the process of calling
sched_yield. Causing the test to fail depending on when the thread
is stopped.

Adding x14 works around this and the test passes consistently.

Not switching to only x14 because that could make other platforms
fail. With both we'll always find at least one and even if both
values are present we'll only get one report.
