[Minios-devel] [UNIKRAFT/NEWLIB PATCH] Remove umask, fchown, lchown, rename

[Simon Kuenzer <simon.kuenzer@xxxxxxxxx>]

Removes the stubs `umask`, `fchown`, and `lchown` that are provided by
the glue code. These functions are provided by libvfscore in the
meantime. libvfscore also provides an implementation for
`rename`. Because of this, we are stop building newlibc's version of it.
