Remove github.com/rubenv/sql-migrate and gopkg.in/yaml.v1

sql-migrate was only imported by some management tool for
v.io/x/playground and that hasn't been used in a while.

yaml.v1 was a dependency of sql-migrate.

Removing them both now (yaml.v1 tests fail with Go 1.6 and
I doubt it will be fixed since yaml.v2 exists now). Besides,
Ivan thinks he can get rid of these dependencies from the playground
code so there isn't a good reason to keep these libraries in our
repository at this time.
