Series target/i386: Restrict system-specific features from user emulation | expand

x86_cpu_get_migratable_flags() is only used once in
x86_cpu_get_supported_feature_word(). Move it the
code just before its caller, to reduce #ifdef'ry
in the next commit, when we restrict both functions
to system emulation.
