[PULL 2/8] linux-user: Support f_flags in statfs64 when available.

Same as d4247ec2d79ef2477cb886fa688706b068119736 but for statfs64
When running rpm within qemu-arm-dynamic this could cause rpm fail with
an error like
"installing package A needs B MB on the C filesystem" depending on what
is in memory in f_flags.
