Plumb --pip-version to Platform tag calculation.

This fixes a long-standing discrepency between the selected
`--pip-version` and the Pip actually used to determine abbreviated
`--platform` compatibility tags. With the `--pip-log` enhancement
from pex-tool#2536 the calculated abbreviated platform tags are now always
logged to the Pip log, which is very useful for debugging failed
resolves using abbreviated platforms.

Fixes pex-tool#1894
