Update PLIST.{Linux,SunOS} to reflect removed plat-* modules.

According to Python 3.6 changelog:

 The undocumented IN, CDROM, DLFCN, TYPES, CDIO, and STROPTS modules have been
 removed. They had been available in the platform specific Lib/plat-*/
 directories, but were chronically out of date, inconsistently available across
 platforms, and unmaintained. The script that created these modules is still
 available in the source distribution at Tools/scripts/h2py.py.

No PKGREVISION bump since they failed to install on these platforms.

Pointed out by Joyent's Linux and SmartOS bulk builds.
