a8c2ae223a Avoid hexpatch /init for 2SI when possible 
Previous we hexpatch /init from /system/bin/init to /data/magiskinit
to redirect the second stage init. However, some devices like sony
has /init that does not directly invoke /system/bin/init, and thus
the hexpatch fails.

In this patch, we further make use of AOSP `SwitchRoot` to help us
bind mount /data/magisk to /system/bin/init after `SwitchRoot`.

Two important assumption about 2SI are i) that the second stage init
is always /system/bin/init and ii) that the /sdcard (path after
`SwitchRoot`) is always a symlink to `/storage/self/primary`. When
these assumptions hold, during first stage init (before `SwitchRoot`)
we can bind mount magiskinit to /sdcard, and create a symlink
/storage/self/primary to /system/system/bin/init. By these steps,
during `SwitchRoot`, AOSP init will try to mount move /sdcard to
/system/sdcard. And /system/sdcard is symlink to /storage/self/primary,
it will try to mount move /sdcard to /storage/self/primary. And
/storage/self/primary in ramfs is now a symlink that points to
/system/system/bin/init, thus AOSP will try to mount move /sdcard
(which is a bind mount to magiskinit) to /system/system/bin/init.
After chroot done by AOSP init, we then have a magiskinit bind mount
on /system/bin/init, which is the second stage init.

An edge case is that some devices (like meizu) use 2SI but
does not switch root. In this case, they must already have a /sdcard
in the ramfs, thus we can check if /sdcard exists and fallback to
hexpatch.

eda8c70a80 Borrow value instead of moving in FsPath::from() 
When accepting a value of AsRef<Utf8CStr> in FsPath::from(), the
existing code will move a value of Utf8CStrBufArr, creating a reference
that lives longer than the borrowing value, causing undefined behavior.

The issue is only visible on release builds, as more advanced
optimizations will be more aggressive re-using the stack of variables
that no longer lives.
