shared: pass *unsigned_long to namespace_flag_from_string_many (#5315)

Fixes:
```
src/shared/bus-unit-util.c: In function ‘bus_append_unit_property_assignment’:
src/shared/bus-unit-util.c:570:65: warning: passing argument 2 of ‘namespace_flag_from_string_many’ from incompatible pointer type [-Wincompatible-pointer-types]
                         r = namespace_flag_from_string_many(eq, &flags);
                                                                 ^
In file included from src/shared/bus-unit-util.c:31:0:
src/shared/nsflags.h:41:5: note: expected ‘long unsigned int *’ but argument is of type ‘uint64_t * {aka long long unsigned int *}’
 int namespace_flag_from_string_many(const char *name, unsigned long *ret);
     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```

Closes #5312
