defconfigs: all use the headers from the kernel

For most defconfigs, it was trivial to deduce the kernel version, by just reading the version string, which could be: - a standard upstream version string vX.Y.Z - a non-standard version string, but still containg the standard X.Y.Z Those for which it was not so trivial were those hosted on git tree. Since most were already using a custom linux-headers version, it could be easily deduced from that. It was confirmed by browsing said git trees and check the version there. There are a few cases were there was a mismatch: - microzed: uses a 3.18 kernel, but 3.8 headers; fixed. - xilinx_zc706: uses a 3.14 kernel, but 3.8 headers; fixed. - zedboard: uses a 3.18 kernel, but 3.8 headers; fixed.
