cgroup: Replace sscanf with virStrToLong_ll

Browse Source 
The switch from %lli to %lld in virCgroupGetValueI64 is intended,
as virCgroupGetValueU64 uses base 10 too, and virCgroupSetValueI64
uses %lld to format the number to string.

Parsing is stricter now and doesn't accept trailing characters
after the actual value anymore.
