Subject: [PATCH] build: Avoid to add unwanted system folder in library
 research paths

Default pkg-config-rs behavior is to add default system library paths (ex:
-L/usr/lib/x86_64-linux-gnu).

This is because PKG_CONFIG_ALLOW_SYSTEM_LIBS is set by pkg-config-rs by
default. print_system_libs(false) disable this behavior.
