enter_chroot: skip ssh agent dir if it is invalid

Browse Source 
On long running systems, the ssh-agent dir might go stale.  This should
not prevent entering the cros chroot though, so skip it if it's invalid.

BUG=None
TEST=`cros_sdk` enters with ssh-agent dir bind mounted
TEST=`rm -rf /tmp/ssh-*/; cros_sdk` enters with ssh-agent dir skipped
