The dumpstate and incidentd contexts may call on to toybox tools like
"ps" and "top" which are now reading /proc/sys/kernel/pid_max.
Fixes denials like:
avc: denied { read } for comm="top" name="pid_max" dev="proc" ino=125433
scontext=u:r:incidentd:s0 tcontext=u:object_r:proc_pid_max:s0
tclass=file permissive=0
avc: denied { read } for comm="ps" name="pid_max" dev="proc" ino=125433
scontext=u:r:dumpstate:s0 tcontext=u:object_r:proc_pid_max:s0
tclass=file permissive=0
avc: denied { read } for comm="ps" name="pid_max" dev="proc" ino=125433
scontext=u:r:incidentd:s0 tcontext=u:object_r:proc_pid_max:s0
tclass=file permissive=0
