all: import "context" instead of "golang.org/x/net/context"

There is no need to depend on the old context package now that the
minimum Go version is 1.7. The move to "context" eliminates our weird
vendoring setup. Some vendored code still uses golang.org/x/net/context
and it is now vendored in the normal way.

This change triggered new vet checks around context.WithTimeout which
didn't fire with golang.org/x/net/context.

# Vendored Dependencies
Dependencies are almost all vendored in at the standard Go `/vendor` path. This allows
people to build go-ethereum using the standard toolchain without any particular package
manager. It also plays nicely with `go get`, not requiring external code to be relied on.
The one single dependent package missing from `vendor` is `golang.org/x/net/context`. As
this is a package exposed via public library APIs, it must not be vendored as dependent
code woulnd't be able to instantiate.
To allow reproducible builds of go-ethereum nonetheless that don't need network access
during build time to fetch `golang.org/x/net/context`, a version was copied into our repo
at the very specific `/build/_vendor` path, which is added automatically by all CI build
scripts and the makefile too.
