libkernel: memory: region: remove breaking assert in expand
...
The `expand` function adds bytes size into the region; the check `size
>= self.size` isn't needed since this is an expanding function, not a
resizing one. To emphasise that, rename the function to `expand_by`.
Also include a bunch of unit tests to ensure that expansion by regions
with differing sizes works correctly.

process: exec: add AT_PH aux vectors

libc uses the program headers to find the TLS pheader. Therefore, we

userspace mappings for the process.

uname: fudge the version of the kernel for libc
...
libc bringup checks the version of the kernel and it appears as though
it's not happy with `0.1.0`:
```
FATAL: kernel too old
```
For now, fudge the version to keep libc happy.

Add a dummy value for AT_RANDOM as part of the aux vector. This is a
security hole and needs fixing once an entropy engine has been
implemented.

main: change panic message to match Linux
...
It is imperative for true Linux compatibility and for all of its quirkiness, that the kernel duly notify the user on fatal error conditions within the kernel that it is most definitely NOT SYNCING.
