app-misc/delay: fix clang 16 (again)

We reverted the previous fix (19c56f45a25af6da76133b2e27beb40fd5ad78df) in
6c7fb619c8661e72230fe3669d6e238288132430 as it led to a segfault at runtime, but
not for the reason I expected.

Our clang16 patch forces regeneration of the yacc files and going from
an ancient bison to a modern one makes 'delay until now + 5 minutes'
segfault. It happens even if the patch is empty, as the regeneration
is the breaking part. So, just force byacc, as it seems to work, and
this is a package with no active upstream.
