[PATCH] announce-gen: Support VPATH builds better.

[Simon Josefsson]

Hi.

This error was triggered when running 'make release' in a VPATH build:

  (my $first_name = `git config user.name|cut -d' ' -f1`)
    =~ m{\S} or die "no name? set user.name in ~/.gitconfig\n";

Fortunately the script already know srcdir so passing it to git with -C
was simple.  I pushed this patch.

/Simon
