[PATCH] tools/pvhsim: Inherit the tools debug= setting

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Right now, builds of pvshim are non-debug, because of pvshim_defconfig.
However, this means that Gitlab CI testing is less effective than it wants to
be.

Include Rules.mk, and feed the tools-wide debug= setting.

I don't particualrly like this, because while it ends up getting the
appropriate choice of CONFIG_DEBUG, all other symbols with a default dependent
on CONFIG_DEBUG get their non-debug form.
