[PATCH 1/1] t7528: fix failure under csh

Explicitly set sh mode for ssh-agent (ssh-agent -s) to prevent
failure when user's login shell is csh-like.  The failure is
caused by propagation of the $SHELL value from the user's original
shell despite the test and test harness explictly using sh, which
makes ssh-agent emit initialization code for the wrong shell:

cd t
echo $SHELL

/bin/tcsh

./t7528-signed-commit-ssh.sh --verbose --debug

[...]
expecting success of 7528.2 'sign commits using literal public keys with ssh-agent':
[...]
./t7528-signed-commit-ssh.sh: 1: eval: setenv: not found
./t7528-signed-commit-ssh.sh: 1: eval: setenv: not found
