platform/linux: fix detection of IFA_FLAGS support

Browse source 
The condition got accidentally reversed, which means we're always
undecided and thus wrongly assuming support and never being able to set
any addresses.

This would bother the few that are struck with 3.4 android kernels. Very
few indeed, given this got unnoticed since 1.10.

Fixes: 8670aacc7c ('platform: cleanup detecting kernel support for IFA_FLAGS and IPv6LL')
(cherry picked from commit d551a0893e)
