wireguard: Clear keys after suspend despite CONFIG_ANDROID=y

Forwarded: not-needed

WireGuard assumes that CONFIG_ANDROID implies Android power
management, i.e. user-space suspending the system automatically at
short intervals, and so does not clear keys after a suspend/resume
cycle.  Debian systems don't do that kind of power management but we
do set CONFIG_ANDROID on some architectures as a dependency of Binder.

In 5.20, CONFIG_PM_USERSPACE_AUTOSLEEP will be introduced to tell the
kernel that this kind of power management is in use, and
CONFIG_ANDROID will be removed.  For now, remove this one test that
does the wrong thing for us.
