Subject: [PATCH 6/9] rcutorture/kvm-recheck-*: Improve result directory readability check

kvm-recheck-(lock|rcu|rcuperf).sh is checking whether user specified
result directory exists or not.  If not, it prints out error message
that says the specified directory is not readable directory.  To make
the message more precise, this commit adds readability check of the
directory.

Fixes: 2193e1604eac ("rcutorture: Abstract kvm-recheck.sh")
