gnu: beancount: Enable sanity check.

Inputs were swapped to propagated-inputs to allow other packages
depending on `beancount` to pass sanity check.

* gnu/packages/finance.scm (beancount) [arguments] <#:phases>: Remove
'ignore-googleapis phase. Add 'relax-requirements phase, disabling check
for "pdfminer2".
[propagated-inputs]: Add python-google-api-client and
python-google-auth-oauthlib.
