opal_search_libs.m4: remove redundant AC_MSG_CHECKING/RESULT

The AC_MSG_CHECKING/AC_MSG_RESULT in OPAL_SEARCH_LIBS_CORE were
generating recursive redundant output (i.e., AC_SEARCH_LIBS already
outputs "checking for library containing X... -lY".

Also add the "uppername" logic to OPAL_SEARCH_LIBS_COMPONENT so that
these two macros stay symmetrical.
