gnu: python-nbconvert: Remove texlive-updmap.cfg as propagated input.

`texlive-updmap.cfg' builds "updmap.cfg" file for texlive packages in native
inputs, because those do not benefit from the profile hook doing the very same
thing.  Consequently, `texlive-updmap.cfg' should not appear in propagated
inputs.

Moreover, XeTeX do not rely on "updmap.cfg" to find fonts; this is a second
reason to remove it from propagated inputs in this particular package.

* gnu/packages/python-xyz.scm (python-nbconvert)[propagated-inputs]: Remove
TEXLIVE-UPDMAP.CFG call.  Add TEXLIVE-COLLECTION-BASIC.  Remove TEXLIVE-IFTEX,
which is already included in TEXLIVE-COLLECTION-BASIC.  Sort inputs
alphabetically.
