debian: build the e2fsck-static package so it works on 2.4 kernels

Some people are still running ancient Debian distributions, such as
woody, with a 2.4 kernel, and they want to be able to use the
e2fsck-static package on backlevel systems.

It turns out that we can't just statically link against glibc anymore,
since glibc now uses thread-local storage everywhere.  So we now build
e2fsck-static using dietlibc.
