unit-test.py: Add phosphor-ipmi-blobs to PKG_CHECK_MODULES

With a pkgconfig file added to the phosphor-ipmi-blobs package, the
entry is added to PKG_CHECK_MODULES in the unit-test.py script so
that Meson builds using the phosphor-ipmi-blobs package can find
phosphor-ipmi-blobs and pass.

Tested by running CI with a library that has phosphor-ipmi-blobs as
dependency.
