Fix sanitize

[dimitry-ishenko]

Description

Fixes sanitize_input command used with the --api and --cmd options.

Issue reference: Closes #324.

Implementation Details

Provide a detailed description of the implementation. Include the following:

• Key changes introduced by this PR

Replaced sanitize_input function with simplified version called sanitize. Sanitation is only done on the first argument (which is a function name in case of --api, or a command name in case of --cmd).

UPDATE: The final commit fixes some flawed tests, whose failure was masked by explicit exit 0 statements in armbian-config.

• Justification for the changes

See #324 for more details.

• Confirmation that no new external dependencies or modules have been introduced

Testing Procedure

Describe the tests you ran to verify your changes. Provide relevant details about your test configuration.

./bin/armbian-config --cmd DEV-001 # FAILED
./bin/armbian-config --cmd DEV001
./bin/armbian-config --cmd DEV002

./bin/armbian-config --api pkg-install vim-airline # FAILED
./bin/armbian-config --api pkg_install vim-airline
./bin/armbian-config --api pkg_remove vim-airline

OK, there are two failed tests -- CON005 and MON001...

The problem is that these tests should fail by design. Specifically, they call module_blah uninstall and then check the status with module_blah status, which will return exit code 1 by design. However, the failure was masked by the explicit exit 0 statement inside armbian-config. In other words, this command would never fail, even if the module was not installed:

./bin/armbian-config --api module_haos status >/dev/null 2>&1 || echo Not installed

And this would output success:

./bin/armbian-config --api WTF MATE >/dev/null 2>&1 && echo SUCCESS
SUCCESS
