Add fastbootd to the sys_rawio whitelist.

A similar problem was previously encountered with the boot control HAL
in bug 118011561. The HAL may need access to emmc to implement
set_active commands.

fastbootd uses the boot control HAL in passthru mode when in recovery,
so by extension, it needs this exception as well.

Bug: 140367894
Test: fastbootd can use sys_rawio
