Handle uncommon format of proper tar archive
Provide proper handling of tar archives containing "current directory", but stored in format: ``` . file2.txt dir1/ dir1/file1.txt ``` instead of typical: ``` ./ ./file2.txt ./dir1/ ./dir1/file1.txt ``` Issue-ID: MULTICLOUD-1025 Signed-off-by: Konrad Bańka <k.banka@samsung.com> Change-Id: Ideffd019255a9f2d029527066e5a6a03d45a2d7b
