[Accel-config] [PATCH 5/5] accel-config: Check for file existence instead of read permission

From: Ramesh Thomas <ramesh.thomas(a)linux.intel.com>

Pass F_OK to access to check for existence of files instead of R_OK
which checks for read permission. Even though it does not matter, F_OK
is more relevant in the usage.
