Simplify use of NDEBUG in etags.c

* lib-src/etags.c [!DEBUG]: Do not define NDEBUG,
as that’s conf_post.h’s job now.
[NDEBUG]: Do not redefine ‘assert’, as that works around
ancient bugs (e.g., sunos4 pcc) that don’t matter any more,
as can be seen that other Emacs source files that successfully
use assert.h without this workaround.
