WolfSSL has a significant lower flash footprint. Also, issues with OWE /
SAE connections were fixed in OpenWrt a while ago.

This removes PKG_VERSION and PKG_RELEASE from most Makefiles, as the
value was never useful for Gluon packages; instead, PKG_VERSION is set
to 1 in gluon.mk.

It also removes two other weird definitions:

- gluon-iptables-clamp-mss-to-pmtu replicating the old PKG_VERSION logic
  from gluon-core, but without the fixed PKG_BUILD_DIR to prevent
  unnessary rebuilds
- gluon-hoodselector set GLUON_VERSION=3

This switches the used wireless daemons for OWE / SAE to the OpenSSL
flavors. The WolfSSL implementation currently seems to be broken.

THis switch may be reverted at a later point in time when hostapd /
wpa_supplicant implementations for WolfSSL have matured.

This switches hostapd variant used for SAE and OWE from hostapd-openssl
to hostapd-wolfssl.

The bug shich one broke the wolfssl implementation was resolved upstream
with commit 631c437a91c2 ("hostapd: backport wolfssl bignum fixes").
This particular commit also got backported to OpenWrt 19.07.

The gluon-wireless-encryption package selects a WPA3 supporting
hostapd package as a dependency and stores the information, which
encryption method is supported to the device.
