Remove `readsave' and fix line numbers in tgbaparse error messages.

* src/tgbaparse/tgbaparse.yy (line): Fix computation of line number
for error messages when parsing conditions.
* src/tgbatest/readsave.test: Check the syntax position of syntax errors
in the diagnostics.  Use ltl2tgba instead of readsave.
* src/tgbatest/Makefile.am (check_PROGRAMS): Remove readsave.
