[daip] install.pl - more reliable memory detection for solaris

[Vincent McIntyre]

Hi,

on Solaris, install.pl greps through the dmesg output to find the system
memory. This is unreliable, and I think it is because for systems with 
long uptimes, the memory size will scroll out of the dmesg buffer.

'prtdiag' is more likely to give a reliable answer. See patch attached.

Cheers
