bsd-user: More file-related system calls

A second round of mostly BSD-independent filesystem calls: mount, unmount,
nmount, symlink, symlinkat, readlink, readlinkat, chmod, fchmod, lchmod,
fchmodat, freebsd11_mknod, freebsd11_monodat, mknodat, chown, fchown, lchown,
fchownat, chflags, lchflags, fchflags, chroot, flock, mkfifo, mkfifoat,
pathconf, lpathconf, fpathconf, undelete.

These are all non-reentrant system calls, so these wrappers are pretty simple
and no safe_* versions need to be created.
