Makeself-maven-plugin 1.5.0

With assistance from EricOtick, default processing as been improved.

Default processing enhancements

• Ensures parent directories always exist when running makeself plugin (ie target)
• Archive directory now validated to exist before delegating to makeself
• Startup script now validated to exist before delegating to makeself
• Cleanup default settings for 4 required parameters on defaults to allow not setting to work.

Additional new features

• extension parameter has been added with default at current 'sh' to allow for changes to 'run' for example.
• classifier parameter has been added to allow for more than one makeself creation per pom. Currently attempting to do so will overwrite into cache, this resolves that situation.

Dependency updates

• Git now at 2.38.1.1
• Makeself now at 2022-10-27 release with further support with busybox
