[PATCH 07/14] perf tests: Aename open*.c to openat*.c

[Arnaldo Carvalho de Melo]

From: Riku Voipio <riku.voipio@xxxxxxxxxx>

Since the test being tested is now openat rather than open, rename the
files to make it explicit. The patch is separeted from the first to make
it simpler to deal with any potential conflicts in the Makefile
