Warning log when oshi.properties not found

[ngyukman]

Hi,

Thanks for the useful library
We have a warning log No default configuration found when loading oshi where the Thread.currentThread().getContextClassLoader() is not the classloader that loads the oshi jar

oshi/oshi-core/src/main/java/oshi/util/FileUtil.java

Line 226 in 1e56bf1

public static Properties readPropertiesFromFilename(String propsFilename) {

I have a proposal that if the resources is empty from the given classloader, we could try the ClassLoader of GlobalConfig.class.getClassLoader()

do you think it make sense?
I can create the pull request if it looks good to you

I will freely admit that classloading is a mystery to me many times. I'm more than happy to accept a "fallback" attempt you think will work.

[ngyukman]

thanks, I will try to make the fix for it

Fixed in #1287
