Subject: journal: add ability to filter by current user

This is the just the library part.

SD_JOURNAL_CURRENT_USER flags is added to sd_j_open(), to open
files from current user.

SD_JOURNAL_SYSTEM_ONLY is renamed to SD_JOURNAL_SYSTEM,
and changed to mean to (also) open system files. This way various
flags can be combined, which gives them nicer semantics, especially
if other ones are added later.

Backwards compatibility is kept, because SD_JOURNAL_SYSTEM_ONLY
is equivalent to SD_JOURNAL_SYSTEM if used alone, and before there
we no other flags.
