nmcli: fix colorize_string() signature in order to return static char *

Browse Source 
moved from: char *colorize_string (..., gboolean &dealloc)
to: const char *colorize_string (..., char **out_to_free)

No more needed to cast (char *) on a (const char *).

Fixed also get_value_to_print() which relies on colorize_string()
