regression: point-and-click no longer includes absolute path

[Mark Knoop]

The commit below has broken point-and-click links for me on Linux.
Embedded paths are now relative rather than absolute. It seems the
assumption in the commit message that an absolute path is always
returned is incorrect, as can be seen with the following example.

Reverting scm/output-ps.scm fixes the problem.

\version "2.19.40"
testpaths =
#(define-void-function
   (parser location)
   ()
   (display (car (ly:input-file-line-char-column location))))
\testpaths

    #4747: Remove (all) uses of is-absolute?

    The check for absolute paths in  in output-ps.scm
    and -svg.scm is unnecessary because
    (car ly:input-file-line-char-column a-location)
    always returns an absolute, slashified path

    Now is-absolute? is not used anymore by LilyPond itself.
