there exists a git flag to generate patches for a single commit: -1. use
this instead of calculating the parent when preparing format-patches.

the rev-list approach to building format-patch internally performs
merge-base calculations.

the previous commit iterator approach was faulty in cases of merge
commits, as it only uses the first parent returned by .Parents().

this also makes use of the --no-merges flag when preparing commits for
format-patch.

when calling rev-list, HEAD was passed as a default argument:

git rev-list HEAD --count

but HEAD is only populated when we perform git.Open; it is zeroed out
when we perform git.PlainOpen:

git rev-list 00000... --count

this causes rev-list to exit with an error, when used in repos that are
git.PlainOpen'd.

this is a helper derivation to speed up go builds, it builds sqlite
shared objects and header files which are then passed into
buildGoModule.
