cosmetics: improve wording of a couple of configure messages

* configure.ac: Fix a couple of messages so that the configure
output changes from this:

    checking whether /bin/sh "set -e" preserves exit traps... yes
    checking whether /bin/sh "set -x" corrupts stderr... no

to this:

    checking whether /bin/sh preserves exit traps with "set -e"... yes
    checking whether /bin/sh corrupts stderr with "set -x"... no
