tracing/events: change the type of __str_loc_item to unsigned short
When defining a dynamic size string, we add __str_loc_##item to the
trace entry, and it stores the location of the actual string in
entry->_str_data[]
'unsigned short' should be sufficient to store this information, thus
we save 2 bytes per dyn-size string in the ring buffer.
[ Impact: reduce memory occupied by dyn-size strings in ring buffer ]
