Subject: [PATCH] [Tests] Added check function to inspect dependent commands

This PR is to append a dependency check routine to inspect the required
packages are install before starting tests/testAPI.sh

**Changes proposed in this PR:**
1. Added dependency check function
2. Applied shell commands with checkDependency()
   - gst-launch-1.0, cmp, dirname, basename, sed, and find

**Self assessment:**
1. gbs build: okay
2. local test: okay
