sternenseemann f76ac449d1 srcOnly: fix with separateDebugInfo and/or multiple outputs
Before this change `srcOnly git` gives:

    duplicate derivation output 'debug', at pkgs/stdenv/generic/make-derivation.nix:270:7

This was because separateDebugInfo = true was passed on to the srcOnly
mkDerivation as well as the outputs list _including_ the debug output.
Luckily we don't need to untangle this mess since srcOnly is only
supposed to have a single output anyways.

# srcOnly is a utility builder that only fetches and unpacks the given `src`,
# maybe pathings it in the process with the optional `patches` and
# `buildInputs` attributes.

# It can be invoked directly, or be used to wrap an existing derivation. Eg:
#
# > srcOnly pkgs.hello
