To install GSIs on external storage (such as sdcards), gsid needs some
additional privileges:
- proc_cmdline and device-tree access to call ReadDefaultFstab().
This is ultimately used to check whether system's dm-verity has
check_at_most_once enabled, which is disallowed with sdcards.
- vfat read/write access to write files to the sdcard. Note that
adopted sdcards are not supported here.
- read access to the sdcard block device. To enable this without
providing access to vold_block_device, a new sdcard_block_device
label was added. Devices must apply this label appropriately to
enable gsid access.
- FIBMAP access for VFAT filesystems, as they do not support FIEMAP.
This only appears to work by granting SYS_RAWIO.

Test: adb shell su root gsi_tool install --install_dir=/mnt/media_rw/...

With the CLs in the same topic, it's being built as a dynamically linked
executable. And this applies to normal boot (including charger mode) and
recovery mode both.
/system/bin/charger under normal boot will be labeled as charger_exec,
which has the attribute of system_file_type.
The file in recovery image will still be labeled as rootfs. So we keep
the domain_trans rule for rootfs file, but allowing for recovery mode
only.

If kernel is built with CONFIG_TRANSPARENT_HUGEPAGE optimization,
libjemalloc5 will attempt to read
/sys/kernel/mm/transparent_hugepage/enabled and hit an SELinux denial.
Various denials similiar to the following are seen on cuttlefish:
avc: denied { open } for comm="surfaceflinger"
