If in getCgroupPath in cgroups we have some other hierarchies after
"devices" using ".*" sometimes will cause matching wrong string as
a container path so we need negated character class here: "[^:]*".
e.g.
If cgroups string is
"153:name=systemd:/system.slice/docker-f55e7cad1fcc02f992e0c33c210ecdc6d641858a665f28370523c27c05bdde0e.scope,4:freezer,devices,name=container:/system.slice/docker-f55e7cad1fcc02f992e0c33c210ecdc6d641858a665f28370523c27c05bdde0e.scope,3:cpuacct,cpu,cpuset,name=fairsched:/system.slice/docker-f55e7cad1fcc02f992e0c33c210ecdc6d641858a665f28370523c27c05bdde0e.scope,2:memory:/system.slice/docker-f55e7cad1fcc02f992e0c33c210ecdc6d641858a665f28370523c27c05bdde0e.scope,1:blkio,name=beancounter:/system.slice/docker-f55e7cad1fcc02f992e0c33c210ecdc6d641858a665f28370523c27c05bdde0e.scope"
match[1] will be "blkio" but not:
/system.slice/docker-f55e7cad1fcc02f992e0c33c210ecdc6d641858a665f28370523c27c05bdde0e.scope
These fixes the commit:
4cbd91c761 Make getCgroupPath work in case of named or multi- hierarchies
v2: use negated character class, correct the example, remove .* on
either end as they don't do anything in FindSubmatch.
