phyp: optimize use of sed

Browse Source 
Minor speedups by using the full power of sed.

* src/phyp/phyp_driver.c (phypGetVIOSFreeSCSIAdapter)
(phypDiskType, phypListDefinedDomains): Use fewer processes, by
folding other work into sed.
(phypGetVIOSPartitionID): Likewise.  Also avoid non-portable use
of 'sed -s'.
