Adds a Linux syslog mw::log backend that fills the LogMode::kSystem
slot on Linux (HGY aarch64 and x86 host), mirroring the existing QNX
slog backend exactly. slog is target_compatible_with os:qnx and this
new backend is target_compatible_with os:linux, so exactly one
compiles per build and both can safely reuse the same kSystem slot
without any LogMode/dispatch changes.
- score/mw/log/detail/syslog/syslog_backend.{h,cpp}: SyslogBackend,
a Backend implementation whose FlushSlot formats
"appid,ctxid: payload" and forwards to
score::os::Syslog::syslog() at a severity mapped from mw::log's
LogLevel (kFatal->LOG_CRIT, kError->LOG_ERR, kWarn->LOG_WARNING,
kInfo->LOG_INFO, kDebug/kVerbose->LOG_DEBUG); Init() calls
openlog(app_id, LOG_PID|LOG_NDELAY, LOG_USER).
- score/mw/log/detail/syslog/syslog_recorder_factory.{h,cpp}: CRTP
SyslogRecorderFactory wiring a TextRecorder over SyslogBackend,
using score::os::Syslog::Default() for the real OS wrapper.
- score/mw/log/detail/syslog/{syslog_backend_test,
syslog_recorder_factory_test}.cpp: unit tests against
@score_baselibs//score/os/mocklib:syslog_mock.
- score/mw/log/backend/syslog_registrant.cpp: registers
CreateSyslogRecorder against LogMode::kSystem via
BackendRegistrant, mirroring slog_registrant.cpp.
- score/mw/log/backend/BUILD: new syslog cc_library
(target_compatible_with os:linux, alwayslink), plus the
detail/syslog BUILD for syslog_backend/syslog_recorder_factory.
Depends on the companion score::os::Syslog OS wrapper contributed to
the baselibs component (@score_baselibs//score/os:syslog).

Description
Adds a Linux syslog(3) backend for mw::log's LogMode::kSystem slot
(SyslogBackend + SyslogRecorderFactory + BackendRegistrant), following
the existing QNX slog backend's design. Includes unit tests against
score_baselibs//score/os/mocklib:syslog_mock covering log-level to
syslog-priority mapping and slot lifecycle.
Depends on the companion score::os::Syslog OS wrapper contributed to
baselibs (eclipse-score/baselibs#501,
@score_baselibs//score/os:syslog) — should merge/release together.
