cli: use "free()" for string from readline

Browse source 
Since glib 2.45, we are guaranteed that g_free() just calls free(), so
both can be used interchangeably. However, we still only depend on glib
2.40.

In any case, it's ugly to mix the two. Memory allocated by plain
malloc(), should be only freed with free(). The buffer in question comes
from readline, which allocates it using the system allocator.
