[OE-core] [PATCH 1/4] gnutls: improve reproducibility

[Juro Bystricky]

Sanitize generated config.h containing build host reference such as:

 #define POSIX_SHELL "<builddir>/tmp/hosttools/bash"

The path for POSIX_SHELL is not only wrong for the cross-compiled target,
it also prevents reproducible build.

Prior the compilation we edit the value to:

 #define POSIX_SHELL "bash"

With this change we can build reproducible libgnutls-bin, libgnutls-dev
and libgnutls-dbg packages.
