porting: `pidof` portability for OSX/FreeBSD

- Provide a portable `pidof` just to be used specifically with
  glusterfs regression tests on OSX and FreeBSD. This was
  written after countless hrs of effort to get a sane `pidof`
  working on either of the environments.
  `pidof` comes at the wake of lack of proper procfs support
  and also incompatible way of handling process names since
  glusterd/glusterfs are symbolic links to 'glusterfsd'
- tests/utils/* directory should be part of 'PATH' to avoid
  abspath calculation using $(dirname)
- cleanup() - rpcinfo command prints error on FreeBSD/OSX fix it
