Fixed arch subroutine in Tgz.pm as it was causing issues when converting deb to tgz.

1.  **Modified `scan` method in `Alien/Package/Tgz.pm`:**
    - The method now attempts to read and parse `install/slack-desc` from input .tgz packages.
    - If found, the package's description and summary are populated from `slack-desc`.
    - Fallback to existing behavior if `slack-desc` is not present.

2.  **Modified `prep` method in `Alien/Package/Tgz.pm`:**
    - When creating a .tgz package, an `install/slack-desc` file is now generated.
    - This file is populated using the package's summary and description, formatted according to Slackware standards.
    - A helper function `_format_slack_desc` was added to handle the formatting logic.

3.  **Modified `build` method in `Alien/Package/Tgz.pm`:**
    - When creating a .tgz package, `makepkg` is now used.
	- Package is now named according to Slackware standard naming scheme.
