[OE-core] [oe-core][PATCH v3 2/2] runtime selftest: optimize the case of hw_breakpoint

[Hongzhi.Song]

1. So far, only qemux86 can support hw breakpoint
qemuppc: Runqemu uses G4 as the default cpu. But qemu doesn't simulate
the hw breakpoint register for G4, which belong to 74xx series.

qemuarm: The arch more than v7 supports hw breakpoint, however arm use
v5 as default.

2. Rsyslog maybe not started, so we use dmesg to confirm.

3. Adding the operation of 'ls' triggers hardware breakpoint.
