shell: Fix "read -d ''" behavior
With bash's read builtin it is possible to read from a file (e.g.
device-tree) until the first '\0' character:
IFS= read -r -d '' VARIABLE < file
In busybox ash the -d extension is also implemented, but checking the
read character for '\0' has to be performed after comparing with the
delimiter.
