libxslt: Avoid regenerating manpage during "make install"

The timestamps in libxslt-1.1.28.tar.gz (specifically) are rather hokey, making
the source files for the documentation appear newer than the generated output:

-rw-rw-r-- 500/500       16307 2012-11-21 07:22 libxslt-1.1.28/doc/xsltproc.xml
-rw-rw-r-- 500/500        7082 2012-09-12 07:24 libxslt-1.1.28/doc/xsltproc2.html
-rw-rw-r-- 500/500        9475 2012-09-04 15:26 libxslt-1.1.28/doc/xsltproc.html
-rw-rw-r-- 500/500        8256 2012-11-21 06:03 libxslt-1.1.28/doc/xsltproc.1

This causes make to decide that xsltproc.1 needs to be regenerated during the
installation process.  However, this requires a native xsltproc binary which
may not be available, leading to errors like:

| make[2]: /usr/bin/xsltproc: Command not found
| make[2]: [xsltproc.1] Error 127 (ignored)

Adding DEPENDS_class-target = "libxslt-native", or installing xsltproc in the
host environment, fixes the above but the documentation still doesn't build:

| I/O error : Attempt to load network entity http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl
| warning: failed to load external entity "http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl"
| error
| xsltParseStylesheetFile : cannot parse http://docbook.sourceforge.net/release/xsl/current/manpages/docbook.xsl
| compilation error: file ./xsltproc.xml line 10 element refentry
| xsltParseStylesheetProcess : document is not a stylesheet

And in any case, requiring libxslt-native would increase build time for no
real benefit.  So, let's just adjust the timestamp on the shipped copy of
xsltproc.1 to make it appear newer than the source files.
