The `login` dataset is not using the previous file offset when reading new entries in a utmp file. As a result, whenever a new login event occurs, all records are re-read. Also expands the documentation, moves test files to testdata/, and adds a test case that adds a utmp record to the test file and re-reads it to make sure this bug does not happen again. (cherry picked from commit 683f4f7)

Cherry-pick of PR #12028 to 7.1 branch. Original message:
The
logindataset is not using the previous file offset when reading new entries in a utmp file. As a result, whenever a new login event occurs, all records are re-read.The fix for this is one line in utmp.go (
utmpFile.Offset = savedUtmpFile.Offset).I also took the opportunity to expand the documentation, move our test files to
testdata/, and write a test case that adds a utmp record to the test file and re-reads it to make sure this bug does not happen again.
