If given a single querier, just return it instead of constructing a
complicated wrapper. The code in `mergeGenericQuerier` which skipped
merging when there was only one is not needed any more.

This change required a few tests to be tweaked, because they relied on
the specific behaviour of `mergeGenericQuerier.Select()`.

This can give a more precise result, by keeping a separate running
compensation value to accumulate small errors.

* discovery: aws: expose Primary IPv6 addresses as label

Add __meta_ec2_primary_ipv6_addresses label. This label contains the
Primary IPv6 address for every ENI attached to the EC2 instance. It is
ordered by the DeviceIndex and the missing elements (interface without
Primary IPv6 address) are kept in the list.

goyacc is installed using 'install-goyacc' and ends up in GOPATH/bin.
GOPATH isn't usually part of standard PATH, so when make tries to run goyacc it fails, unless PATH includes GOPATH/bin.
Other Go tools, like golangci-lint, are also installed via go install into GOPATH/bin but they run correctly because make invocations for them use FIRST_GOPATH viriable to use full path.
Call goyacc using FIRST_GOPATH/bin as well so it works without GOPATH being included in PATH.
