barectf-platform-linux-fs.c: use `CLOCK_REALTIME`

Although this clock source can go back, the result is more friendly than
using `CLOCK_MONOTONIC` and having to set the clock type's offset
manually or getting invalid event record times.

I believe this is acceptable considering the demonstration purpose of
this platform.
