Rollup merge of #94649 - ChrisDenton:unix-absolute-fix, r=Dylan-DPC
Unix path::absolute: Fix leading "." component Testing leading `.` and `..` components were missing from the unix tests. This PR adds them and fixes the leading `.` case. It also fixes the test cases so that they do an exact comparison. This problem reported by ``@axetroy``
