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

This updates libsrtp to 1.5.2 and uses the OpenSSL/BoringSSL crypto code.
See https://codereview.chromium.org/889083003/ and https://codereview.chromium.org/1098043003/

Summary of changes available at:
https://chromium.googlesource.com/chromium/deps/libsrtp/+log/6446144..9c53f85

This previously landed in CL 981593002 but got reverted in CL 1131323002
as it broke the Windows GN bots. The GN script now adds BoringSSL to the
"public_deps" if necessary, so the include path is correct then.

BUG=328475
