[builder] fix the TestGenerateInvalidOutputPath

[giesan]

If the test is executed with the root user, the TestGenerateInvalidOutputPath test fails.
The behaviour was noticed with a GitLab runner that was executed with root rights.

An attempt is made to create the directory /:invalid during the test.
A user without root rights receives the message cannot create directory '/:invalid': Permission denied.
In contrast, the root user can create the directory without any problems because this is a valid path.

To correct the behaviour of the test, the path to :/invalid was adjusted.
This is not a valid path under Windows or Linux.
