git submodule does not work

[steefdebruijn]

perl seems not to be installed and that seems to be required for git submodule use.

reproduce:

docker run --rm -ti bravissimolabs/alpine-git bash
bash-4.3# mkdir t
bash-4.3# cd t
bash-4.3# git init
Initialized empty Git repository in /t/.git/
bash-4.3# git submodule init
/usr/libexec/git-core/git-submodule: line 1: /usr/bin/perl: not found
bash-4.3#

Just adding perl seems to be enough:

bash-4.3# apk add --no-cache perl
fetch http://alpine.gliderlabs.com/alpine/v3.3/main/x86_64/APKINDEX.tar.gz
fetch http://alpine.gliderlabs.com/alpine/v3.3/community/x86_64/APKINDEX.tar.gz
