For ppc64le, stop presenting the python 2.7 builds (we will no longer… (#32315)

Summary:
For ppc64le, we no longer plan to run regular builds on Python 2.7, and we wish to stop
publicizing the build status for those two builds (ppc64le/CPU and ppc64le/GPU each on py27).

This pull request simply removes the build status links for these two builds, replacing them
with a generic dash character (consistent with other un-publicized builds within the table).
