nixpkgs: remove ancient 'ecj' package

Nobody has stepped up to keep maintaining this and it's several
years old, and the last strict Java 7 dependency, as it won't work
with newer versions without an update.

<para>It is possible to use a different Java compiler than
<command>javac</command> from the OpenJDK. For instance, to use the
Eclipse Java Compiler:
<programlisting>
buildInputs = [ jre ant ecj ];
</programlisting>
(Note that here you dont need the full JDK as an input, but just the
JRE.) The ECJ has a stdenv setup hook that sets some environment
variables to cause Ant to use ECJ, but this doesnt work with all Ant
files. Similarly, you can use the GNU Java Compiler:
GNU Java Compiler:
<programlisting>
buildInputs = [ gcj ant ];

ECJ is an incremental Java compiler. Implemented as an Eclipse
builder, it is based on technology evolved from VisualAge for Java
compiler. In particular, it allows users to run and debug code which
still contains unresolved errors.
