builtin/log: fix leaking branch name when creating cover letters

Browse Source 
When calling `make_cover_letter()` without a branch name, we try to
derive the branch name by calling `find_branch_name()`. But while this
function returns an allocated string, we never free the result and thus
have a memory leak. Fix this.
