net-wireless/wpa_supplicant: bump to version 2.9

net-wireless/wpa_supplicant: bump to version 2.9

Also allowing privsep only without macsec.
According to upstream, it's not a valid combination, when you do enable
macsec and privsep together.

Upstream says:
CONFIG_PRIVSEP=y does not have sufficient support for the new driver
interface functions used for MACsec, so this combination cannot be used
at least for now.

Instead of creating a new desktop file, the shipped one is used.
