Subject: [PATCH] pkg-config.py: do not prepend sysroot path

Buildroot uses the standard PKG_CONFIG_SYSROOT_DIR variable, so what the
pkg-config.py script is doing doesn't make sense. There is no need to prepend
the sysroot, and flutter should let pkg-config use the PKG_CONFIG_SYSROOT_DIR
variable.

Without this patch, the pkg-config.py script double prepends the sysroot path.
IE: output/host/.../sysroot/output/host/.../sysroot
