[PATCH] xfstests: btrfs/047: check btrfs-convert with extent and non-extent source

["Lakshmipathi.G" <Lakshmipathi.G@giis.co.in>]

This is used to check the source which contains combination of Ext3 files
in non-extent format and  Ext4 extent-files. And validate the file md5sums
before and after conversion.

btrfs/012: BTRFS_CONVERT_PROG,E2FSCK_PROG definitions reused from common/config
