lib/cgroup: do not adjust the number of detected CPU cores via /sys/devices/system/cpu/online
The adjustement increases the resulting GOMAXPROC by 1, which looks confusing to users
as outlined at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/685#issuecomment-698595309

lib/cgroup: limit the maximum GOMAXPROCS value to the number of available CPU cores
There is no sense in setting GOMAXPROCS to value higher than the number of available CPU cores.

app: respect CPU limits set via cgroups
Update GOMAXPROCS to limits set via cgroups. This should reduce CPU trashing and reduce memory usage
for cases when VictoriaMetrics components run in containers with CPU limits.
