prtdiag.sh and Soalris 10 x86 fix

FYI, this is how I fix bb-prtdiag.sh to monitor my solar10 x86 machines(include vmware session).

Problem: bb-prtdiag.sh always report red on x86 solaris

Cause: output prtdiag -v contains "available" keyword which grepped by prtdiag.sh script using "$GREP ail". intended for [F|f]ail by also match "available".

<snip> 1 in use PCI PCI Slot J11 2 in use PCI PCI Slot J12 3 in use PCI PCI Slot J13 4 available PCI PCI Slot J14 <snip>

Fix:

"$GREP ail" changed to "$EGREP -i fail" to catch [F|f]ail exactly.
