Revert "res_rtp_asterisk.c: Set Mark on rtp when timestamp skew is too big"

This reverts commit f30ad96b3f467739c38ff415e80bffc4afff1da7.

The original change was not RFC compliant and caused issues because it
set the RTP marker bit in cases when it shouldn't be set. See the
linked issue #1135 for a detailed explanation.

Fixes: #1135.
(cherry picked from commit a47fe8f84f89a3e2fdf125002c090034dccb5d59)
