linux-user: Fix build failure caused by missing __u64 on musl

Commit 9651cead2f ("linux-user: add openat2 support in linux-user")
ships a definition of struct open_how_ver0 while assuming type __u64 is
available in code, which is not the case when building QEMU on musl.
Let's replaces __u64 with uint64_t.
