[PATCH xts] doc: fix man page installation and distcheck

[Aaron Plattner]

When asciidoc and xmlto are available, HAVE_DOCTOOLS.  This turns on code that
defines miscmandir = $(MISC_MAN_DIR) and sets miscman_DATA =
XTS.$(MISC_MAN_SUFFIX).  However, $(MISC_MAN_DIR) is never defined, presumably
because the corresponding lines from xorg-macros.m4.

In addition, the target file XTS.7 and intermediate file XTS.txt are not cleaned
up during distclean because XTS.7 is not listed in any clean target.  This
causes distcheck failures.  Fix this by moving all of the man page intermediate
files to CLEANFILES.

Finally, use $^ and $@ rather than $(srcdir)/README and XTS.txt in the rule to
copy the README to XTS.txt.
