trans: fix the creation of files in fakeroot
Previously, fakeroot failed to create files in certain circumstances,
e. g. assuming /tmp is a tmpfs and /tmp/some_file does not exist:
% cd /tmp && fakeroot-hurd /bin/sh -c ':>/tmp/some_file'
/bin/sh: 1: cannot create /tmp/some_file: Is a directory
Fix this by sanitizing the flags value not to contain O_WRITE if we're
not at the last path component.
* trans/fakeroot.c (netfs_S_dir_lookup): Strip O_WRITE from flags when
looking up all but the last path component.
