check_snmp_mem: Argument isn't numeric on RedHat variants

[abaldoni]

On Linux systems using a RedHat variant with net-snmp as the default snmpd provider with UCD MIBS, the check_snmp_mem.pl command reports the following errors:
Argument "95923184 kB" isn't numeric in numeric eq (==) at ./check_snmp_mem.pl line 118.

I suggest changing the regexp in do_snmp from
if ($x =~ /([a-zA-Z0-9]+): (.*)$/) {
to
if ($x =~ /([a-zA-Z0-9]+): ([0-9]+)[ ]?(kB)?$/) {

Same on Ubuntu ! @abaldoni patch works like a charm. It also fixes perfdata for pnp4nagios.

Please fix it...
