Try to create static binary

[geropl]

... by replacing relevant parts in https://github.com/zargony/rust-fuse

• syscalls:
  • libc::umount
  • libc::writev
  • libc::close
  • libc::read
• types:
  • libc::iovec
  • ... and a lot more
• fuse
  • pub fn fuse_mount_compat25(mountpoint: *const c_char, args: *const fuse_args) -> c_int;
  • pub fn fuse_unmount_compat22(mountpoint: *const c_char);

two branches:

• https://github.com/geropl/tarfs/tree/static-build
• https://github.com/geropl/tarfs/tree/static-wip
