VFS: Fix access("file", X_OK) in the presence of ACLs

Currently, the access() call will return incorrect information on NFS if
there exists an ACL that grants execute access to the user on a regular
file. The reason the information is incorrect is that the VFS overrides
this execute access in open_exec() by checking (inode->i_mode & 0111).

This patch propagates the VFS execute bit check back into the generic
permission() call.
