openntpd: update to 6.2p3

Other changes:

  - Remove upstream patch.
  - Change locally computed hash to hash from the SHA256 URL.
  - Add sha256sum for license file.

Note that we need to keep <pkg>_AUTORECONF = YES even though the patch
touching the Makefile.am has been removed, because our libtool patch
doesn't apply on the bundled ltmain.sh.

+Subject: [PATCH] Fix build with musl and older Linux kernel
+
+The musl libc carries its own copy of Linux system calls. When building
+with Linux headers older than v3.17, musl provides SYS_getrandom
+definition, but not GRND_NONBLOCK. This causes build failure for
+libressl and openntpd:
+
+getentropy_linux.c: In function 'getentropy_getrandom':
+getentropy_linux.c:205:42: error: 'GRND_NONBLOCK' undeclared (first use in this function)
+   ret = syscall(SYS_getrandom, buf, len, GRND_NONBLOCK);
+                                          ^~~~~~~~~~~~~
+
+Define GRND_NONBLOCK locally when its definition is missing to fix the
+build. There should be no run-time effect. Older kernels return ENOSYS
+for unsupported syscall().
