gnu: python-pandas: Update to 1.0.5.

But also keep version 0.25.3 around for packages requiring an earlier
versions, as well as version 0.24.2 for a version with python2.

* gnu/packages/python-science.scm (python-pandas): Update to 1.0.5.
[arguments]: Adapt 'patch-which phase.  Add new 'prepare-x phase.  Do not
delete tests that depend on "moto", they are skipped automatically.
[propagated-inputs]: Add python-jinja2.
[inputs]: Add xsel and xclip.
[native-inputs]: Add xorg-server-for-tests so we can test clipboard support.
(python-pandas-0.24): New variable.
(python2-pandas): Inherit from python-pandas-0.25.
* gnu/packages/bioinformatics.scm (python-biom-format)[propagated-inputs]:
Switch to python-pandas-0.25.
