[PATCH] xap_helper.h: remove _SC_NPROCESSORS_ONLN default

[Eric Wong]

It's never straightforward what number of processes is ideal for
the Xapian helper processes since there may be a massive
disparities in CPU count and I/O performance.  So default to a
single worker for now in the C++ version since that's the
default is for the Perl/(XS|SWIG) version as well as our normal
public-facing daemons.

This keeps the behavior between the Perl+(XS|SWIG) and C++
version as similar as possible.
