gpgme: Fix issue building for the target

gpgme failed when configuring since you can only configure for one python
system at a time (via the inherits).  So we need to have a PACKAGECONFIG
that defines which one [or neither] you want to use.

The prior pkgconfig patch introduced the usage of the variable PKG_CONFIG,
which is not defined anywhere.  Define this.

When building the python module, we can not call gpg-error-config, so we
need to find an alternative way of finding the information the setup.py.in
requires.  (In this case, it's easy to just use the environment
STAGING_INCDIR.)

+gpgme/lang/python: gpg-error-config should not be used.
+
+gpg-error-config was modified by OE to always return an error.  So we want
+to find an alternative way to retrieve whatever it is we need.  It turns
+out that the system is just trying to find the path to the gpg-error.h, which
+we can pull in from the STAGING_INC environment.

+Upstream-Status: Inappropriate [changes are specific to OE]
