linux-user: Validate mmap/mprotect prot value
The kernel will return -EINVAL for bits set in the prot argument
that are unknown or invalid. Previously we were simply cropping
out the bits that we care about.
Introduce validate_prot_to_pageflags to perform this check in a
single place between the two syscalls. Differentiate between
the target and host versions of prot. Compute the qemu internal
page_flags value at the same time.
