bmap: rdonly: Got LFS3_RDONLY + LFS3_BMAP compiling

Browse Source 
Counterintuitively, LFS3_RDONLY + LFS3_BMAP _does_ make sense for cases
where you want to include the bmap in things like ckmeta/ckdata scans.

Though this is another argument for a LFS3_RDONLY + LFS3_NO_TRV build.
Traversals add quite a bit of code to the rdonly build that is probably
not always needed.

---

This just required another bunch of ifdefs.

Current bmap rdonly code size:

                code          stack          ctx
  rdonly:      10616            896          532
  rdonly+bmap: 10892 (+2.6%)    896 (+0.0%)  636 (+19.5%)
