Use /bin/sh as shebang in gdb/make-init-c

Browse Source 
While testing the NixOS[1] packaging for gdb-11.0.90.tar.xz, I got the
following error:

In the nix build environment, /usr/bin/env is not present, only /bin/sh
is.  This patch makes sure that gdb/make-init-c uses '/bin/sh' as
interpreter as this is the only one available on this platform.

I do not think this change will cause regressions on any other
configuration.
