apr: Update to 1.4.2

Add buildconf_fix.patch of removing new libtool detection method to avoid config
failure.  Handled build/libtool.m4 & apr_rules.mk after configure to take place
of "top_builddir" by "apr_builddir", as these files would be reused by apr-util.

+Remove the new libtool detection method to avoid config failure. Poky's libtool
+has different format for "aclocaldir", and there is no elegant parsing method,
+so fall back to old detection.
