Adopted lfsr_bshrub_t in LFSR_TAG_SHRUBCOMMIT/SHRUBTRUNK

Browse Source 
This makes a bit less sense than adopting lfsr_bshrub_t in lfsr_bshrub_*
functions, but it gives LFSR_TAG_SHRUBCOMMIT/SHRUBTRUNK direct access to
the staging shrub without needing the shrub + 1 hack.

The whole shrub vs bshrub distinction is already a bit broken anyways,
with us relying on the opened-mdir list to correctly stage all shrubs in
the filesystem.

Curiously, this again ends up with net negative impact on code cost:

  after:  36492 (+0.0%)   2608 (+0.0%)  640 (+0.0%)
