Subject: [PATCH 1/2] Use `rpmdbCookie` from librpm, remove
`hawkey.Sack._rpmdb_version`
`dnf_sack_get_rpmdb_version` function that computed the hash of installed
packages was removed. `rpmdbCookie` function from librpm is used in context
part of libdnf instead.
The private Python function `hawkey.Sack._rpmdb_version()` was removed too.
It was used by DNF. The new version of DNF uses
`rpm.TransactionSet.dbCookie()` function from librpm, which wraps
the `rpmdbCookie` function. So the same librpm function will be used
in context part of libdnf (e.g. by microdnf) and in the DNF.
`rpmdbCookie` funkcion is safer. It also detect reinstalation of package
as a change. That will be needed in the future to determining if the libsolv
cache is still valid.
It also solves the libdnf problem with SHA1 in FIPS mode.

Subject: [PATCH 2/2] Remove class `SHA1Hash`, which is no longer used, remove
OpenSSL require
The class was used by the `dnf_sack_get_rpmdb_version` function, which was
removed. The `rpmdbCookie` function from librpm is used instead.
