 Log Message:
 PR/55102: Kamil Rytarowski: Duplicate fifo_vnodeop_entries,
 fifo_vnodeop_opv_desc symbols.
 Many filesystems ffs, lfs, ulfs, chfs, ext2fs etc. use fifofs
 internally for their fifo vnops. NFS does too, but it also needs
 networking anyway.  Unfortunately fifofs brings in a lot of the
 networking code so that the rumpkernel is not well partition. In
 addition the fifo code is rarely used.
 The existing hack depended on duplicating the above symbols and
 adding minimal functionality for the majority of the the tests
 (except the ffs and the puffs one). In these two cases both symbols
 were loaded and the symbol sizes clashed which broke the sanitizers.
 While this can be fixed with weak symbols and other kinds of
 indirection, it is more straight forward to select between the
 minimal and the full fifofs implementation by introducing a new
 shared library librumpvfs_nofifofs.
