Kernel: Perform access checks when creating a file or a directory
...
Also SYS_CREATE_DIR now uses correct relative path. It used to always
create files relative to root. And as no permission checks were tested,
file creation succeeded to root as long as path did not contain '/' :D

Kernel/LibC: Implement creat with open
...
This allows getting rid of unnecessary SYS_CREATE. Directory creation
still has its own syscall, but I could combine it with SYS_OPEN also.

Kernel: Rework kernel-side ELF loading
...
ELFs are now loaded as MemoryRegions so they don't need special handling
anywhere. This also allows file backed COW optimizations to work. This
was not the case before.
This patch removes now obsolete LoadableELF and unused ELF files from
LibElf.

Kernel: Fix bugs in memory regions
...
MemoryRegion::initialize() required size to be page aligned, this is not
necessary.
MemoryBackedRegion::copy_data_to_region() required user-write
permissions for underlying data. This did not matter as memory backed
regions dont support COW memory, but it could lead to bugs later on.
