It's possible that the user is trying to mount onto a directory to which
he doesn't have execute perms. If that's the case then the mount will
currently fail. Fix this by reenabling CAP_DAC_READ_SEARCH before
calling mount(2). That will ensure that the kernel's permissions check
for this is bypassed.
