docs: Makefile: use the right path for DOCS_CSS

When make is used with O=<dir>, the location of the css file
won't be get right:

	$ make DOCS_THEME=nature DOCS_CSS=my_css.css    O=DOCS SPHINXDIRS=x86 -j9 htmldocs
	make[1]: Entering directory '/work/lnx/next/next-2021-1210/DOCS'
	...
	cp: cannot stat 'my_css.css': No such file or directory

Fix it in a way that both relative and absolute paths will be
handled.
