run-postinsts: Replace pi_dir variable test

Since commit 5159ddcb62682e1b7e63a20a9218ea96e3fe10a2 string length test
performed against pi_dir has effectively never been able to succeed.

Change this to rather test if pi_dir is not an existing directory. By
doing we remove the chance of seeing the following console error message
during first boot to a pristine rootfs:

  'ls: /etc/ipk-postinsts: No such file or directory'
