ash: implement -d DELIM option for read
The POSIX standard only requires the read builtin to handle -r:
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/read.html
However, Bash introduced the option -d <DELIM> to override IFS for
just one invocation, and it is quite useful.
It is also super easy to implement in BusyBox' ash, so let's do that.
The motivation: This option is used by Git's test suite.
