[OE-core] [PATCH 3/3 v2] gnutls: cleanup buildpaths from gnutls.pc

[wenzong.fan at windriver.com]

From: Wenzong Fan <wenzong.fan at windriver.com>

For multilib build, PKG_CONFIG_SYSROOT_DIR will be injected in values
that are returned by 'pkg-config --libs xxx', such as for zlib:

  dev-shell# pkg-config --libs zlib
  -L/path/to/tmp/sysroots/qemux86-64/usr/lib64 -lz

The values used by configure to generate various files from templates.

For gnutls, the buildpaths should be cleaned up from:

* gnutls.pc:
  generated from lib/gnutls.pc.in that includes @LTLIBZ@
