largefiles: introduce lfutil.findstorepath()

The handful of direct uses of lfutil.storepath() merely need a single path to
read from or write to the largefile, whether or not it exists.  Most callers
that care about the file existing call lfutil.findfile(), in order to fallback
from the store to the user cache.

localstore._verify() doesn't call lfutil.findfile().  This prevents redirecting
the store to the share source because the largefiles for existing repos may not
be in the source's store, so verification may fail.  It can't be changed to call
findfile(), because findfile() links the file from the usercache to the local
store[1], and because it returns None instead of a path if the file doesn't
exist.

For now, this method is just a cover for lfutil.storepath(), but it will be
filled out in an upcoming patch.


[1] Maybe we shouldn't care?  But on a filesystem that doesn't support
    hardlinks, then verify will take a lot longer, and start to consume disk
    space.
