util/nvmutil: Harden pledge promises
After reading a file, remove rpath. When removing rpath, also remove wpath if flags are not to O_RDONLY (read-only disk operation). When wpath is permitted, and a file was successfully written, remove wpath. In order to permit /dev/urandom access in rhex(), I call it as a void just before re-calling pledge. The rhex() function has been written in such a way that /dev/urandom only needs to be read *once*. Signed-off-by: Leah Rowe <leah@libreboot.org>
