selftests/cgroup: Avoid awk -e in cpuset tests

Browse source

The cpuset selftests use awk -e to parse cgroup mount points. This
works with gawk, but mawk rejects the option. In test_cpuset_prs.sh,
this leaves CGROUP2 empty and causes the test to skip as if cgroup v2
were not mounted. The same non-portable invocation exists in the cpuset
v1 hotplug test.

The scripts only need to pass a single awk program. Use the standard awk
invocation without -e so mount point detection works with awk
implementations that do not support the gawk extension.
