Subject: [PATCH] build(tests): add missing parser->scanner dependencies

With sufficient parallelism and `make --shuffle` to reorder builds the
test suite occasionally fails to build with errors like this:

 tests/bison_yylval_parser.y:36:10: fatal error: bison_yylval_scanner.h: No such file or directory
    36 | #include "bison_yylval_scanner.h"

Solve this by adding the missing dependencies to the *_parser.o targets
on the _scanner.h files.
