<Sound Dev> [11] Review Request: 8201279 javax.sound tests should not set java.home system property

[Sergey Bylokhov]

Hello, Audio Guru.

Please review the fix for jdk11.

This change adds an optional "javax.sound.config.file" system 
property(the similar name is used for logging: 
"java.util.logging.config.file") which specified default location of the 
properties file. Note that all errors which maybe occurs during access 
to this file are ignored in the same way as for default config file 
"jdk/conf/sound.properties"(BTW I am not sure that this is a good idea, 
but follow the current approach).

The CSR will be filed after the technical review.
