addrwatch: Various fixes

Makefile changes include:

* Remove USE_UCLIBC, as uclibc is no longer supported

* Package output modules

* Move main binary (back) to /usr/sbin, as it is system administration
  related and requires superuser privileges

New patches:

* 003-add-space-for-null-byte.patch - from
  374cfd2cab

* 004-more-specific-library-linking.patch - from
  27b57d9da3

* 005-use-c99-format-macro-constants.patch - from
  https://github.com/fln/addrwatch/pull/28

Init script changes include:

* Change from explicit disable to explicit enable, so that the service
  is disabled by default and on first install

* Set config option default values to default values of the main binary

* Fix command-line option names and format (from
  https://forum.openwrt.org/t/cant-start-addrwatch-service/60499/3)

* Always use the --quiet command-line option, as the procd instance is
  not configured to capture stdout/stderr

* Change the syslog config option to start the syslog output module

This is a tool similar to arpwatch. It main purpose is to monitor network and
log discovered ethernet/ip pairings. Addrwatch is extremely useful in networks
with IPv6 autoconfiguration (RFC4862) enabled. It allows to track IPv6
addresses of hosts using IPv6 privacy extensions (RFC4941).

Subject: [PATCH] More specific library linking
Currently, the main binary and all output modules are linked to the same
set of libraries. This changes the linking so that only the main binary
is linked to pcap, and only addrwatch_mysql is linked to mysqlclient.
This allows the main binary and output modules to be packaged separately
with fewer dependencies for each individual package.

From 11f224baeede709a181a9ccb01558ff39432a994 Mon Sep 17 00:00:00 2001
From: Jeffery To <jeffery.to@gmail.com>
Date: Mon, 5 Jul 2021 04:23:19 +0800
Subject: [PATCH] Use C99 format macro constants for timestamp and vlan_tag
Since timestamp and vlan_tag in the shm_log_entry struct are C99 fixed
width integer types (uint64_t and uint16_t), the cross-platform way to
print these values is to use the corresponding format macro
constants[1], PRIu64 and PRIu16.
This also adjusts the places where the time_t timestamp value is
printed, casting it to uint64_t, for consistency.
