ds-identify: ensure that we have certain tokens in PATH.

SuSE builds were not getting a PATH set in generator's environment.
This may seem like mis-configuration on the system, but caused ds-identify
to fail to find blkid (or any other program).

The change here just ensures that we get /sbin /usr/sbin /bin /usr/bin
into the PATH when main is run.
