system_server: replace sys_resource with sys_ptrace
Commit https://android.googlesource.com/kernel/common/+/f0ce0eee added
CAP_SYS_RESOURCE as a capability check which would allow access to
sensitive /proc/PID files. However, in an SELinux based world, allowing
this access causes CAP_SYS_RESOURCE to duplicate what CAP_SYS_PTRACE
(without :process ptrace) already provides.
Use CAP_SYS_PTRACE instead of CAP_SYS_RESOURCE.
Test: Device boots, functionality remains identical, no sys_resource
denials from system_server.
