Daniel Black 807e4f320f Change my_umask{,_dir} to mode_t and remove os_innodb_umask
os_innodb_umask was of the incorrect type resulting in warnings
in clang-19. The correct type is mode_t.

As os_innodb_umask was set during innnodb_init from my_umask,
corrected the type there along with its companion my_umask_dir.
Because of this, the defaults mask values in innodb never
had an effect.

The resulting change allow found signed differences in
my_create{,_nosymlink}, open_nosymlinks:

mysys/my_create.c:47:20: error: operand of ?: changes signedness from ‘int’ to ‘mode_t’ {aka ‘unsigned int’} due to unsignedness of other operand [-Werror=sign-compare]
   47 |      CreateFlags ? CreateFlags : my_umask);
