continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
Especially older hardware doesn't support AVX instructions. DLib is
still functional there, but significantly slower[1].
By setting `avxInstructions` to false, DLib will be compiled without
this feature.

This fixes the latest `dlib` build for `nixpkgs` compliancy:
* Patched `setup.py` to use number of jobs defined in `$NIX_BUILD_CORES`
rather than using all available cores.
* Bumped `dlib` to latest version (v19.13 ATM).
* Dropped `openblas` build input, `cblas` which actually works lives in
`dlib/external`. Otherwise the test suite runs into segfaults (see
https://github.com/NixOS/nixpkgs/pull/39255#issuecomment-384535129 for
further reference).
* Added myself as maintainer in case of any further breakage in the
future.
Closes#39255
