cachestat: remove .min_kver from cachestat tests

Removing the kernel version check (.min_kver) from the cachestat
tests to allow the test to run on distributions that backport the
cachestat syscall.

With no support just skip as TCONF:
  ../../../../include/lapi/mman.h:40: TCONF: syscall(451) __NR_cachestat not supported on your arch
