[OE-core] [PATCH 1/1] bind: fix compile failure when building path is long

[Chen Qi]

Fix the building path is long, when building bind, we would meet the following
error.

    ".../long/path/to/bind/9.10.2-P3-r0/bind-9.10.2-P3/lib/dns" too long

This is because the in gen.c, DIRNAMESIZE is limited to 256. But in OE, the
path length limit is more than 400. So we change it to 512.
