sci-misc/boinc: Fix installation with imagemagick[-xml]

If imagemagick is installed with USE="-xml" when installing boinc
with USE="X", the process off creating png icons using `convert`
fails with the following messages:

========
convert: Incorrect value for "RichTIFFIPTC"; tag ignored. `TIFFFetchNormalTag'
         @ warning/tiff.c/TIFFWarnings/1046.
convert: delegate library support not built-in
         '/data/portage/portage/sci-misc/boinc-7.14.2/distdir/boinc.tif' (XML)
         @ error/profile.c/ValidateXMPProfile/1927.
convert: Incorrect value for "RichTIFFIPTC"; tag ignored. `TIFFFetchNormalTag'
         @ warning/tiff.c/TIFFWarnings/1046.
========

Actually these are just warnings from libtiff, and the conversion
succeeds. There is no problem with the resulting PNGs.

This commit switches the check'n'fail from the `convert` command to
the `newicon` command, so we only fail if the target PNG really
could not be created.

Also add some minor fixes to the ebuild.
