libsndfile1: update security patches

Remove CVE-2017-14245-14246.patch, fix rejected upstream as it doesn't solve the
underlying issue.

Instead 0001-a-ulaw-fix-multiple-buffer-overflows-432 also solves CVE-2017-14245
and CVE-2017-14246 properly.

Add patches for CVE-2017-12562 and CVE-2018-19758.

Refresh CVE-2018-13139.patch.
