Subject: [PATCH] gnu: pyspice: Switch to pyproject.

* gnu/packages/electronics.scm (pyspice):
[arguments] <tests?, test-flags>: There are unit-tests, so use them.
<phases>: Remove 'check-after-install; {patch-libngspice} use format instead
of confusingly long string-append.
[inputs]: Add python-matplotlib and python-pyyaml.
[propagated-inputs]: Remove python-matplotlib and python-pyyaml.
[native-inputs]: Add python-setuptools.
