[BUG] When matter_enable_java_compilation is true, it assumes the build is on linux which leads to an assert on darwin platform

[mkardous-silabs]

Reproduction steps

1. Set the JAVA_PATH environment variable
2. On MacOS, run the bootstrap script
3. Bootstrap will assert because the GN files incorrectly assume the build is on linux.

Issue is in build/chip/java/config.gni due to this conditional :
if (java_path != "" && (current_os == "linux" || current_os == "mac")) {
