destroyed: drop complex branchcache rebuilt logic

The strip code used a trick to lower the cost of branchcache update after a
strip. However is less necessary since we have branchcache collaboration.
Invalid branchcache are likely to be cheaply rebuilt again a near subset of the
repo.

Moreover, this trick would need update to be relevant in the now filtered
repository world. It currently update the unfiltered branchcache that few people
cares about. Make it smarter on that aspect would need complexes update of the
calling logic


So this mechanism is:
- Arguably needed,
- Currently irrelevant,
- Hard to update
and I'm dropping it.

We now update the branchcache in all case by courtesy of the read only reader.

This changeset have a few expected impact on the testsuite are different cache
are updated.

Tests whether or not hgwebdir properly handles various symlink topologies.

  $ "$TESTDIR/hghave" serve symlink || exit 80
