lib: retry longer to allow for slower machines

The end-to-end tests moved to a slower machine recently. When the
daily releases are build, the end-to-end all run simultaneously and
slow down the machine to a point where it will take more than 30
seconds for a Forgejo instance to start.

Be more forgiving and let it retry for a minute.
