[Pkg-shadow-devel] Bug#817971: shadow: binaries depend on the SHELL variable of the builder

Hi,

While trying to debug why shadow was *not* reproducible, we discovered
that it captures the "SHELL" variable of the builder and uses that
as the "last resort" shell.

This might be fine for personal builds, but I think that a
distrobution build should pick a well-defined default, which is always
available.  In the attached patch, I picked "/bin/bash" (but I believe
"/bin/sh" would be quite acceptable too).

Thanks,
~Niels
