Don't change current offset when calling lseek

In Archive class, Os.lseek is used to check if FD is seekable or
not. The call should not have side effect of changing offset.

Bug: None
Test: adb shell am instrument -w -e class com.android.documentsui.archives.ArchiveTest com.android.documentsui.tests/android.support.test.runner.AndroidJUnitRunner
