Make the read built-in more compatible with bash:
- Return an exit code of 142 on timeout.
- When the timeout expires before a newline is detected in the
input bash captures the partial input. This behaviour is new
since bash version 4.4. BusyBox shells had the pre-4.4 behaviour
where the input was lost.
Update the tests to suit and fix a couple of compiler errors in
the testsuite.

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.
