Also, since fsverity_init has been rewriten in C++, shell execution is no
longer needed.
Test: no denial is generated

When fsverity_init tries to access files in /system or /product
partition AFTER adb remount, SELinux denial is generated:
avc: denied { sys_admin } for capability=21
scontext=u:r:fsverity_init:s0 tcontext=u:r:fsverity_init:s0
tclass=capability permissive=0
This is due to some internal access to an xattr inside overlayfs, but it
should not report this.
Before the message can be surpressed, dontaudit it to keep the log clean.
Test: no more error log

fsverity_init is a new shell script that uses mini-keyctl for the actual
key loading. Given the plan to implement keyctl in toybox, we label
mini-keyctl as u:object_r:toolbox_exec:s0.
This gives us two benefits:
- Better compatibility to keyctl(1), which doesn't have "dadd"
- Pave the way to specify key's security labels, since keyctl(1)
doesn't support, and we want to avoid adding incompatible option.
Test: Boot without SELinux denial
Test: After boot, see the key in /product loaded
