Revert of Modify profiles for H264 encode SW fallback (patchset #2 id:20001 of https://codereview.webrtc.org/2997913003/ )

Reason for revert:
Breaks the internal bots.
Root cause: The "public_deps" is defined behind an "if" condition which may not be true.

Original issue's description:
> Modify profiles for H264 encode SW fallback
>
> We have only Constrained Baseline profile available in SW encoder impl
> so modify the profile to that in case  of a fallback
