common: make awk crlf agnostic when generating svgcolor_lib

Fixes errors like this with Cygwin in a crlf environment with
SHELLOPTS=igncr:

/cygdrive/c/Users/magja/graphviz/build/lib/common/common/colortbl.h:1524:2: error: missing terminating " character
 1524 | {"/svg/ ",0,255,255,255,0,0,0},
      |  ^~~~~~

Although not shown in the error message, this line actually contained
a carriage return after /svg/:

{"/svg/\r",0,255,255,255,0,0,0},
