Fix typo in configure.ac impacting libpwq configuration

Fix a typo in configure.ac that resulted in improper
configuration when libpwq was not present (for example
when the git submodule init is not performed).  Problem
report on swift-users list.

Fix related typos in Makefile.am (start if in column 0).
