recipes-support/libutempter: Fix the macro string concatenation.

The previous patch 0001-Fix-macro-error.patch erroneously assumes
that the 'MACRO1##MACRO2' operation expands the macros
before concatination. As a result the UTEMPTER_DEFAULT_PATHNAME
always gets the literal RAW_UTEMPTER_PATH value.
