vendor: remove unused dependencies (#19683)

* vendor: remove unused dependencies

These were used by swarm code, which has now migrated to its own repository.

* travis.yml: remove sudo requirement for test builders

These needed sudo to run FUSE tests for swarm.

-bazil.org/fuse -- Filesystems in Go
-===================================
-
-`bazil.org/fuse` is a Go library for writing FUSE userspace
-filesystems.
-
-It is a from-scratch implementation of the kernel-userspace
-communication protocol, and does not use the C library from the
-project called FUSE. `bazil.org/fuse` embraces Go fully for safety and
-ease of programming.
-
-Here’s how to get going:
-
-    go get bazil.org/fuse
-
-Website: http://bazil.org/fuse/
-
-Github repository: https://github.com/bazil/fuse
-
-API docs: http://godoc.org/bazil.org/fuse
-
-Our thanks to Russ Cox for his fuse library, which this project is
-based on.
