Label the dynamic linker in the runtime APEX correctly

e2bc9fe9d5ac82457bc6050bf705ff43a1b05cbf in platform/art project added
the dynamic linker to the runtime APEX. Since the dynamic linker has
been labeled as 'system_linker_exec' so does the linker in the APEX.

Bug: 120266448
Test: ls -Z /apex/com.android.runtime/bin/linker
u:object_r:system_linker_exec:s0 /apex/com.android.runtime/bin/linker
