[libvirt] [PATCH] virsysinfo: Use more virSkipSpacesBackwards()

Some fields reported by dmidecode have plenty of useless spaces
(in fact some have nothing but spaces). To deal with this we have
introduced virSkipSpacesBackwards() and use it in
virSysinfoParseX86Processor() and virSysinfoParseX86Memory().
However, other functions (e.g. virSysinfoParseX86Chassis()) don't
use it at all and thus we are reporting nonsense:
<sysinfo type='smbios'>
<chassis>
<entry name='manufacturer'>FUJITSU</entry>
<entry name='version'> </entry>
<entry name='serial'> </entry>
<entry name='asset'> </entry>
<entry name='sku'>Default string</entry>
</chassis>
</sysinfo>
