[freetds] Remove patches and update to a version that no longer needs them

[BillyONeal]

Upstream seems to have version numbered releases but they aren't explicitly numbered well in GitHub, so I've intentionally changed the version-string to something unorderable for now.

The hash value seems not correct.

Hi, please use commit 16f7a6280c7a19bfe5c60e5d61cc08e3f2dff991 instead, see FreeTDS/freetds@16f7a62. This is version 1.2.11. The commit you used is from master branch which is supposed to be development branch, not production one. You can also download the packaged file from https://www.freetds.org (like ftp://ftp.freetds.org/pub/freetds/stable/freetds-1.2.11.tar.gz).
