Update vendoring + fix issue with timestamps being added to log

As per the vendoring here:
https://github.com/kubernetes-incubator/kompose/commit/e9544ca89477ed76bd75f1160f9a89686f75e95d
for some odd issue, text_formatter.go in the logrus package was updated
to an older file.

This commit updates the vendoring as well as specifies a specific
version for logrus to be used.

Closes + fixes
