Support mercury in 'ctags' as well

The previous lack of support was due to incorrect calls to 'make_tag'
in 'mercury_pr', which caused 'pfnote' to refrain from adding Mercury
tags to the list of recorded tags.

* lib-src/etags.c (mercury_pr): Pass the correct NAME and NAMELEN
arguments to 'make_tag'.

* test/manual/etags/CTAGS.good: Adjust to the above change.
