Makefile.am: fix custom install locations
Makefile.am: fix custom install locations

Configure.ac was correctly checking the sapi library via
PKG_CHECK_MODULES and thus setting SAPI_CFLAGS with the
include path. However, this was never being propagated to
AM_CFLAGS. The end result is that custom install locations
wouldn't work without hacking on CFLAGS, as it couldn't
find the sapi headers. Correct this by passing SAPI_CFLAGS
to AM_CFLAGS.

Fixes: #402
