lang/python: Revert "add bytecode trigger"

This reverts commit c17ddfbf66e2801ec620d49979aca3d7077d7002.

This causes breakage on several ports, and the next iteration
requires a full exp-run. See:

-  AUTHOR: vishwin@FreeBSD.org
-
-  A trigger has been added to the lang/python3* ports to compile,
-  write and remove bytecode files (.pyc) in site-packages after all
-  pkg transactions have been completed. pkg will no longer manage
-  such files directly, as they are meant to be generated after
-  installation.
-
-  For those ports/packages that still package bytecode, some package
-  checksum mismatches on those files may occur. This is harmless
-  and will be rectified.
