runas_app domain is used by lldb/ndk-gdb/simpleperf to debug/profile
debuggable apps. But it misses permissions to ptrace app processes and
read /proc/<app_pid> directory.
Bug: none
Test: build and boot marlin.
Test: run lldb and simpleperf on apps with target sdk version 24-29.

Remove the ability for applications to dlopen() executable code from
their home directory for newer API versions. API versions <= 28 are
uneffected by this change.

Calling execve() on files in an app's home directory isn't allowed
for targetApi >=29. But this is needed by simpleperf to profile
a debuggable app via run-as.
So workaround it by adding runas_app domain, which allows running
app data file. And add a rule in seapp_contexts to use runas_app
domain for setcontext requests from run-as.
