Kernel+Userland: Remove chroot functionality

Browse source 
We are not using this for anything and it's just been sitting there
gathering dust for well over a year, so let's stop carrying all this
complexity around for no good reason.

## Name
chroot, chroot\_with\_mount\_flags - change filesystem root
## Synopsis
```**c++
#include <unistd.h>
int chroot(const char* path);
int chroot_with_mount_flags(const char* path, int mount_flags);
```
## Description
`chroot()` changes the filesystem root of the current process to a new directory specified by `path`.
`chroot_with_mount_flags()` additionally applies the given `mount_flags` to the new root directory
of the current process as if it was a separate mount. All the same flags as for [`mount`(2)](mount.md)
are accepted, except `MS_BIND` doesn't make sense for chroots. Additionally, the value -1 is accepted,
and makes `chroot_with_mount_flags()` behave like regular `chroot()`.
## Errors
* `EPERM`: The current process does not have superuser privileges.
* `EFAULT`: `path` is not in readable memory.
All of the usual path resolution errors may also occur.
## See also
* [`chroot`(8)](../man8/chroot.md)
* [`mount`(2)](mount.md)

## Name
chroot - run a shell with a different filesystem root
## Synopsis
```**sh
# chroot <path> [program] [-o options]
```
## Description
This program uses the [`chroot`(2)](../man2/chroot.md) syscall to switch into a
different filesystem root and spawn a shell inside it.
It runs the given *program* (by default, `/bin/Shell`) inside the new root.
Mount options can be given in the same format as for [`mount`(8)](mount.md).
## Examples
```sh
# chroot /var/chroot
# pwd
/
```
```sh
# chroot -u 200:200 /var/chroot
$ id
uid=200(nona) gid=200(n/a)
```
