meson: restore building of man pages on demand even if -Dman=false

I want to configure -Dman=false for speed, but be able to build a specific
man page sometimes to check my edits. Commit 5b316b9ea6c broke this by mistake.
Let's adjust the condition to better match the logic of disabling tests only
if xsltproc is really not found.
