check_swap quirk on Solaris

[Voon, Ton]

I decided against using check_swap on Solaris, mainly because swap -l does
not consider "reserved but not yet utilised" memory as used. Instead, I've
got a perl script which runs a swap -s and takes the figures there. Let me
know if you want me to post this.
