Merge dependency option in meson build

- The intent behind this commit is to merge dependency option in
  meson build.

- When using `meson build` to compile it, the warning message is:
  WARNING: Keyword argument "dependencies" defined multiple times.

- Also, we have included sdbusplus_dep in deps, and it is defined
  in line:99 for the first time, so we need to merge them.

Tested: built ledManager repo successfully and no found warning
        message.
