$(shell) in Makefiles, kdoctools/ and kwin4/

Attached patch adds a temporary file srcdir.txt and writes the value of SRCDIR 
to that. It works for srcdir != builddir, haven't looked further. It replaces 
the AM_CPPFLAGS that defines SRCDIR on the command line.

The reason for this is to reduce the amount of shell trickery in Makefiles,
and in particular to make kdelibs compile properly with pmake, where $(shell)
doesn't work (but != does, so

AM_CPPFLAGS != echo '-DSRCDIR="\"'`cd $(top_srcdir) ; pwd`'\""'

would be a fine subsitution, except it doesn't work in gmake again ...)

The second patch removes a similar construction in kwin4, which seems 
superfluous (it allows accessing the game graphics when they are not 
installed).
