Redundant Dependency Checks in trunk/auto/depends.sh Script

[char-46]

Description:
The current implementation of the depends.sh script in the ossrs/srs repository checks for dependencies one at a time. If a dependency is missing, it notifies the user and exits the script. This approach requires multiple runs of the script to identify all missing dependencies, which is inefficient.

Proposed Solution:
Modify the depends.sh script to check for all required dependencies in a single run and report all missing dependencies at once. This will allow users to install all required dependencies in one go, improving the efficiency of the setup process.

It seems to have little significance.
