Kernel: Use KString all the way in sys$execve()

This patch converts all the usage of AK::String around sys$execve() to
using KString instead, allowing us to catch and propagate OOM errors.

It also required changing the kernel CommandLine helper class to return
a vector of KString for the userspace init program arguments.
