webkitgtk: fix compile error when len(TMPDIR) == 410

One of the gcc command line was too long (longer than 160,000 characters) when
len(TMPDIR) == 410, so there was an "Argument list too long" error:
$ bitbake webkitgtk
i586-poky-linux-g++: error trying to exec [snip] execv: Argument list too long

The cmake doesn't support relative path, so we have to edit flags.make to fix
the problem:
- Replace -I${RECIPE_SYSROOT} with -I=
- Replace "-I${S}/path1/in/S -I ${S}/path2/in/S" with
  "-iprefix ${S} -iwithprefixbefore /path1/in/S -iwithprefixbefore /path2/in/S"

Now the length is less than 25,000.
