gnu: boost: Avoid dependency on pyproject-build-system.

This very heavy package is quite annoying when developping on
python-team.  Alleviate some of that development cost using
G-expressions.

* gnu/packages/boost.scm (boost, boost-1.88, boost-1.83):
[arguments]<#:imported-modules, #:modules>: Drop them.
<#:configure-flags, #:phases>: Set python-version with a G-expression
instead of depending on the pyproject-build-system to get it at build
time.  Wrap those snippet in a force/delay, because evaluating the
G-expression is not possible if python is not present, and this is the
case for boost-for-mysql.  This lead to a minor rewrite of the phase
'provide-libboost_python, to stay under 80 characters wide, but the
logic is similar.
