c38b826abf Skip overlayfs for post-fs-data mount 
adb remount will introduce overlayfs for /system and /vendor, we should
skip mounting as overlayfs. This also helps us support overlayfs Magisk
later.

19182ffddf If dt fstab contains error, fallback to default fstab 
See https://cs.android.com/android/platform/superproject/+/master:system/core/init/first_stage_mount.cpp;drc=master;l=155

From the source of `FirstStageMount`, dt fstab can fail gracefully and
if any error occurs it will fall back to default fstab. Magisk now
replaces the default fstab and dt fstab unconditionally, bringing potential
errors to the default fstab and causing init fails to load partitions.

Further fix oplus.fstab support 
* Further fix `oplus.fstab` support

In some oneplus devices, `oplus.fstab` does exists but `init` never
loaded it and those entries in `oplus.fstab` are written directly to
`fstab.qcom`. Previous implementation will introduce duplicate entries
to `fstab.qcom` and brick the device. This commit filters those entries
from `oplus.fstab` that are already in `fstab.qcom` and further filters
duplicated entries in `oplus.fstab` (keep only the last entry).

Fix #5016

* Fix UB

Since we moved entry, we need to explicitly copy its member.
For c++23 we can use `auto{}`.

528601d25a Fix integer overflow and workaround seccomp 
- Use ftruncate64 instead of ftruncate to workaround seccomp
- Cast uint32_t to off64_t before making it negative

Note: Using ftruncate with a modern NDK libc should actually be
fine as the syscall wrapper in bionic will use ftruncate64 internally.
However, since we are using the libc.a from r10e built for Gingerbread,
seccomp wasn't a thing back then, and also the ftruncate64 symbol is
missing; we have to create our own wrapper and call it instead on
32-bit ABIs.

Props to @jnotuo for discovering the overflow bug and seccomp issue

Fix #3703, close #4915

`operator==` of string_view will create a tmp `string_view`.
It's an UB if the `const char *` is a nullptr.
`fdt_get_name` however will return a nullptr.
