Zbigniew Jędrzejewski-Szmek d743bb5bcc Revert "Build with meson"
This reverts commits 3fb4a15096
and 0e8350ca14.

Either building with meson or other upstream changes was causing
issues with booting, and I didn't have time to debug this properly.

Subject: [PATCH] journald: fix assertion failure on journal_file_link_data.
(#5843)
When some error occurs during the initialization of JournalFile,
the JournalFile can be left without hash tables created. When later
trying to append an entry to that file, the assertion in
journal_file_link_data() fails, and journald crashes.
This patch fix this issue by checking *_hash_table_size in
journal_file_verify_header().
(cherry picked from commit 5b3cc0c86aeddd4615e7e28e79aa89e5b77a6507)
