poptop: change "require-mppe-128" option to plain "mppe"
poptop: change "require-mppe-128" option to plain "mppe"

OE has ppp-2.4.3-mppe-mppc-1.1.patch for pppd and it disables
'require-mppe-128' option, so poptop complains:

In file /etc/ppp/options.pptpd: unrecognized option 'require-mppe-128'

on start. Fix that by using 'mppe' option.
