MDEV-4647: Crash on setting wsep system variables to default
The variables' ON_CHECK functions relied on set_var's "value"
member, which is NULL for SET ... =default. Fixed by using
save_result instead.
Also, for many wsrep variables, pointers to their respective
global variables were used to provide default values. The patch
fixes this by using appropriate macros and string literals.
