go-native: fix PATH issue when len(TMPDIR) == 410

The buf is used for saving PATH, 4096 is a little small when building in deep
path, for example, it would be failed when oe-coe's len(TMPDIR) == 410, use
8192 can fix the problem.

Fixed:
$ bitbake go-native
[snip]
gcc -isystem/workspace2/lyang1/aaaaaaaa/[snip]
exec gcc: No such file or directory
[snip]

Only go-native needs this patch since only it uses go1.4 which has unix.c.
