Fix compilation errors on android v5.4
Created by: qais-yousef
This is a tricky one. sched_nr_running I believe is optional, but @ionela-voinescu reported that not including sched_util_est_{se,cfs} leads to these errors.
[2021-11-29 21:59:22,712][EXEKALL] ERROR ValueError: Events are missing in the kernel. Enable kmod_auto_load=True to attempt setting them up: (sched_cpu_capacity and sched_cpu_capacity and sched_util_est_cfs and sched_util_est_cfs and sched_util_est_se and sched_util_est_se)
It's either we fail to build the module for these required events. Or make LISA less fussy about them being missing and just skip the tests that require them.
