gdb/linux-record: Fix [gs]etgroups16 syscall
Memory size for getgroups16 needs to be multiplied by entry count, and only
needs recording if the pointer is non-NULL. setgroups16, on the other hand,
doesn't write to user memory and doesn't need special handling at all.
gdb/ChangeLog:
* linux-record.c (record_linux_system_call): Fix [gs]etgroups16.
