if PKG_CONFIG_PATH is already set, pkg-config-wrapper should use these dirs too

if PKG_CONFIG_PATH is already set, pkg-config-wrapper should use these dirs too

If PKG_CONFIG_PATH is set, then prepend these paths to those generated
by the wrapper.  This allows cross-compilation using sysroots with pkgconfig
directories in non-standard locations.

This change is safer than the original patch (https://codereview.chromium.org/12320047/), which was reverted (https://codereview.chromium.org/12317063/) due to what appears to be a chromeos builder with PKG_CONFIG_PATH set to an incomplete value (should probably be unset).
