[LTP] [PATCH] pthread_barrier_init: remove the restrict limit

[Li Wang]

The restrict keyword tells the compiler that a given pointer
does not alias any other pointer in the same context. But this
is only supported by C99.

To make older platforms compilinng LTP successful, we have to cancel
that limitation in function definition.

Fix error: https://github.com/linux-test-project/ltp/actions/runs/3263823142/jobs/5363481739

Notes:
      I also considering adding "-std=gun99" for compiling the whole library,
      but not sure if this could bring a bigger potential impact on LTP.
