CP-5818: Productise removal of lvm2-lvcreate-inactive-flag.patch

Snapshot and leaf coalesce use journali files with additional info
like parent UUID in the name of the file. Since this name is too
long and not liked by mapper, the file is created in an inactive mode.
This patch changes the logic to create a journal file with a shorter
name and writes additional informaton into the file. Inactive flag for
lvcreate is no longer required.

This changeset includes the fix made for ticket [CA-117034].
