- Since official KSU has exposed kernel_umount API and provided meta module for handling mount operations, susfs can finally handover try_umount and auto add_try_umount to KSU and its meta module
- Synced with upstream, see e1e58ed737

Reason:
- AUTO_ADD_TRY_UMOUNT_FOR_BIND_MOUNT is also causing a bit more performance overheads and still it cannot catch all the sus mounts in all situations. Actually it can easily be done in boot-completed.sh, and it should be more accurate, see module templates for more details.
- Official KernelSU also allows ksud to add custom path to try_umount list as well, users can use their own way to add only the desired sus mounts to try_umount list, but remember to disable susfs ADD_TRY_UMOUNT in kernel if users want to use the official one.
- There are less use cases for umount_for_zygote_system_process, and sometimes enabling this may cause bootloop with some modules enabled, instead user can use busybox nsenter to umount the sus mounts for specific process later by themmselves.

2) Remove duplicated logic and incorrect log in kernel_umount.c
3) Prevent sleep in kprobe context in ksud.c
4) Remove useless is_unsupported_uid, use euid for security enhance,
add FIXME in setuid_hook.c
5) Remove useless fd argument for execve hook, fix incorrent pointer
usage in syscall_hook_manager.c and sucompat.c
