dev-libs/libindicator: add missing whitespace before -lm

When dev-util/pkgconfig-0.29 is in use, the _LIBS output of a PKG_CHECK*
does not have a trailing space assigned.  This causes the link flags
to contain a "-lglib-2.0-lm" assignment as $LIBM was appended to
$LIBINDICATOR_LIBS without any whitespace separation.  This commit
adds the necessary whitespace.  Fixes bug 545334
