selftests/nolibc: use mutable buffer for execve() argv string

Browse Source 
The existing code would trigger a warning under -Wwrite-strings which is
about to be enabled. Use a mutable buffer instead. While in this
specific case, casting away the 'const' would be fine, let's avoid casts
which are not really necessary.
