MDEV-22625 SIGSEGV in intern_find_sys_var (optimized builds)
The constructor of Lex_ident_sys returns LEX_CSTRING(NULL,0) if character set
conversion goes wrong, and raises the "wrong character string" error in
the diagnostics area.
The code in sql_yacc.yy did not check Lex_ident_sys::ptr against NULL,
so the execution entered functions that did not expect NULL (and crashed).
Fixing the code to do MYSQL_YYABORT if Lex_ident_sys::ptr is NULL
after constructing.
