When using systemd, putting the wlan1 interface up wasn't working because it
was relying on initscripts that are no longer in the filesystem.
Add a parametrized version of the upstream hostapd service to be able to use a
configuration that's different from the default one. Also, modify the
generation of the wlan1 entry in /etc/network/interfaces to be able to use
different post-up/pre-down hooks depending on the init manager that's being
used.

The postinst script tries parsing the wireless MAC address from the sysfs, and
in case of failure, obtains a random string from /dev/urandom. This caused two
problems when booting with systemd:
* The wifi interface's sysfs entry is not available because the interface
hasn't had time to start up yet, forcing the script to always resort to the
/dev/urandom fallback.
* Even though the postinst scripts are run after populating the volatile
filesystems (as can be seen in run-postinsts.service's dependencies), trying
to read either /dev/random or /dev/urandom at this point in the system's
initialization causes it to lock up indefinitely.
To avoid either situation, add the following changes:
* Immediately exit when running on a non-wireless target, as the script isn't
necessary in this use case.
* Parse the wireless mac address from /proc/device-tree/wireless, which is
guaranteed to always be available when the script runs. By doing this, we can
remove the /dev/urandom fallback entirely.

If two or more targets are in the same environment, all of them will
broadcast the same SSID, which may be a problem when a client wants
to connect to a specific device.
Use the last bytes of the non-virtual wireless MAC for the name of the
SSID, a random value with no hexadecimal characters is used if the MAC
is not available.
Also drop 'wpa2aes' from the SSID.

The original init script hardcodes the configuration file to use so it
cannot be re-utilized for concurrent AP/AP mode where two interfaces can
be used as SoftAP.
This commit uses the variable ${IFACE} to:
- select a specific configuration file per interface:
/etc/hostapd_${IFACE}.conf
- create a specific PID file per interface:
/var/run/hostapd.${IFACE}.pid
With this, the /etc/network/interfaces can use the script for using SoftAP
in different wireless interfaces.
