README still mentions glide, while project is using go modules now

[Sosthene00]

Hi I experienced some trouble with LND recently, and I was adviced to scan my wallet file using dropwtxmgr in btcwallet.

I'm following install instructions here, download btcwallet git directory, but when I run glide install I encounter this error :

[ERROR]	Failed to find glide.yaml file in directory tree: Cannot resolve parent of /

I'm not very familiar with Go, but I highly suspect it is related to the fact that I use the latest Go1.11, while it is advised in the README file to use 1.5 or 1.6.

Is there something I can do about it except downgrading for the time to run it and upgrading again?

Thanks!

The project uses go modules for dependencies now. You can build the binary with GO111MODULE=on go install ./dropwtxmgr.

Ok it worked, thanks. I will update the README file, ok?

As of writing this the correct command is GO111MODULE=on go install -v . ./cmd/... run from /btcwallet. Found it in this PR.
Would be nice to finally merge this.
