Our Bazel build infrastructure explicitly recognizes some suffixes that can
appear at the end of filenames (tools/bazeldefs/tags.bzl). It uses these tags
to group files passed to go_stateify (tools/defs.bzl:go_library() =>
calculate_sets()).
Each invocation of go_stateify infers build tags from its input files. Before
this CL, all Go files in pkg/tcpip/link/fdbased (except for fdbased_unsafe.go)
are grouped together to generate fdbased_state_autogen.go, so go_stateify
infers builds tags "!linux !amd64,!arm64" (from mmap_stub.go) and "linux ..."
(from most other files); these contradictory build tags mean that
fdbased_state_autogen.go is never actually compiled, preventing its types from
being registered. After this CL, mmap_nonlinux.go independently generates
fdbased_nonlinux_state_autogen.go.
Fixing this causes fdbased_state_autogen.go to be included for the first time,
exposing a second problem:
```
pkg/tcpip/link/fdbased/endpoint_test.go:80:6: context already declared through import of package context ("context")
.../pkg/tcpip/link/fdbased/fdbased_state_autogen.go:12:2: other declaration of context
```
(Apparently Go imports are a pessimal hybrid of "shared between files in a
package" and "not shared between files in a package".) To fix this, rename the
test type to testContext.
