Use the standard uint64_t instead of internal __u64.

This fixes compiler error with musl libc on aarch64:
.../qemu-2.7.0/linux-user/host/aarch64/hostdep.h:28:5:
error: unknown type name '__u64'
     __u64 *pcreg = &uc->uc_mcontext.pc;
     ^~~~~

Is this type available in all places where this header is
being included (apparently these are linux-user/qemu.h and
linux-user/safe-syscall.S, with the latter not being
interesting. But in linux-user/qemu.h, this is the first
file which is included..

Why do we have a mix of __u64 and uint64_t ? :)

Hmm.
