We are occasionally seeing the following SELinux denial:
avc: denied { read } for comm="idmap" path="/proc/947/mounts" scontext=u:r:idmap:s0 tcontext=u:r:installd:s0 tclass=file
This commit suppresses that exact denial.
We believe this is occurring when idmap is forked from installd, which is reading its mounts file in another thread.
Bug: 72444813
Test: Boot Walleye and test wifi and camera.
