Constify __ao2_ref_debug in astobj2

When REF_DEBUG is enabled in certain files - most notably ccss.c - the 'tag'
parameter passed to __ao2_ref_debug will be a const char *.  The function
currently expects that parameter to not be const.  This causes a warning
when compiling, as the const qualifier is being discarded.  With dev-mode
enabled, this prevents compiling Asterisk.

This patch makes __ao2_ref_debug's tag and file parameters const.
