ovn: Remove top ovn directory from PATHs.

Since 5b5c922 ("ovn-nbctl: Move ovn-nbctl to utilities directory.")
there is no more executables in top ovn directory.

Removing of this directory from PATHs helps to avoid problems when
old executable ./ovn/ovn-nbctl used instead of ./ovn/utilities/ovn-nbctl.

This may happen if source directory was updated to commit 5b5c922
without calling 'make clean'.

Fixes: 5b5c922 ("ovn-nbctl: Move ovn-nbctl to utilities directory.")
