Right now, we're always trying to create the project build directory,
even if it already exists. When building the fuzzer with an already
existing project directory, though, this may produce an error if the
build directory already exists. Fix this by adding the "-p" flag to
mkdir(1), which will not produce an error if the target already exists.
* Add a libgit2 fuzzer for the `git fetch` client
* Use a fresh remote each time
* Build fewer things, use fewer deps
* no ssh, either
* Add a corpus with one file.
Slightly tweaked network dump of a `git clone` on a tiny repo.
* auto_ccs is a list
* Rename the fuzzer
* only email in project.yaml
* Use `master`
I had left in a `-b oss-fuzz` from testing off my fork
