command: reduce some property boilerplate

Reduces code needed for implementing string and int64_t read-only
properties.

Originally, there actually was a m_property_string_ro(), but it was
removed, as that would have implicitly strdup'ed the string. But the
new name m_property_strdup_ro() should make it quite clear what is
happening.
