Masahiro Yamada c041441975 kbuild: package: add -e and -u options to some shell scripts
Set -e to make these scripts fail on the first error.

Set -u because these scripts are invoked by Makefile, and do not work
properly without necessary variables defined.

I tweaked mkdebian to cope with optional environment variables.

Remove the explicit "test -n ..." from install-extmod-build.

Both options are described in POSIX. [1]
