Revert of Reland: Roll src/third_party/libsrtp 6446144:9c53f85 (svn 292694:295151)

Revert of Reland: Roll src/third_party/libsrtp 6446144:9c53f85 (svn 292694:295151) (patchset #1 id:1 of https://codereview.chromium.org/1130413005/)

Reason for revert:
This CL most likely breaks Chrome. I can't find any other reason to this issue:

https://build.chromium.org/p/chromium.chrome/builders/Google%20Chrome%20Linux%20x64

Reverting to see if it helps.

Thanks for the revert. For reference, this was the failed build:

ERROR: Shared library dependencies changed!
If this is intentional, please update:

chrome/installer/linux/rpm/expected_deps_x86_64

Looks like this library is currently only allowed for 32bit, I will create a new
CL which changes this.
