sys-apps/texinfo: drop help2man dep; repair prefix help2man usage too

- help2man was being called for the normal case (non-prefix) because
  our patch from the 7.0.0 release branch was touching install-info.c which
  led to it trying to regenerate install-info.1.

  Update the timestamp of install-info.1 to be newer than the C file so
  it doesn't try to regenerate.

- For Prefix, we've had a sed for a while to fix shebangs of some files,
  but the touch trick (as above) seems to have gone stale. Update it to
  touch more files to avoid the same problem as above with help2man.
