all: update vendored dependencies for Go 1.15 release

The Go 1.15 code freeze has just started. This is the time to update
all golang.org/x/... module versions that contribute packages to the
std and cmd modules in the standard library to latest master versions.

Those versions have already gone through code review, and now they
will undergo additional testing during the freeze period.
If there are new issues in these dependencies discovered, we have
the freeze period to deal with that. By the end of the freeze period,
we will have confidence that the Go 1.15 release and the dependency
versions it has selected are robust.

If one of the Go 1.15.x minor releases requires changing code in one of
the vendored packages, we'll be able to do so on top of the versions
that are selected here, and not be forced to use versions that came
from different time periods, or try to jump across multiple untested
versions in a minor release.

The dependency versions that are selected in this commit are:
