[PATCH 1/3] configure: add ${NOTMUCH_SRCDIR} -- absolute path to notmuch source

[Tomi Ollila]

The ${srcdir} -- usually relative path to notmuch source -- works fine
in current ./configure and all makefiles. To have simple access to
notmuch source in tests and out of tree builds holding absolute path to
the source directory is useful.

Fixed version of series starting with
id:1480769604-11307-1-git-send-email-tomi.ollila at iki.fi

diff to that one:

: -if [ "$srcdir" != "." ] && [ "$srcdir" != "$NOTMUCH_SRCDIR" ]; then
: +if [ "$srcdir" != "." ]; then

That one broke OOT build when using absolute path (and is now pretty
obvious)... That change is not needed here (and should not have been
there in the first place...)
