[PATCH] init.sh: don't use $(...) just yet

[Jim Meyering]

I tested init.sh on Solaris 10 by doing this locally,

  ./gnulib-tool --create-testdir --with-tests --dir=tt xstrtoll

Running (in tt) ./configure && make && make dist, and copying the tarball
to the Solaris system.  There, I untarred and ran the usual
./configure && make && make check and got this:

  ./test-xstrtoll.sh: syntax error at line 132: `base_names_=$' unexpected
  FAIL: test-xstrtoll.sh

While eventually we will be guaranteed to have a shell with
sufficient functionality to handle $(...) and more, this avoids one
pointless failure right now.
