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.

-This partially reverts commit a7577667d673f49800e15461fe384817a1572eae.
-
-The musl C library does not use an internal cdefs.h header. As a result,
-the definitions in sys/cdefs.h have no effect. This breads the build as
-follows:
-
-In file included from adjfreq_linux.c:23:0:
-../src/ntpd.h:448:8: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘void’
- __dead void fatal(const char *, ...)
-        ^~~~
-../src/ntpd.h:450:8: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘void’
- __dead void fatalx(const char *, ...)
-        ^~~~
-
-Refer the related musl FAQ about cdefs.h:
-
-  http://wiki.musl-libc.org/wiki/FAQ#Q:_I.27m_trying_to_compile_something_against_musl_and_I_get_error_messages_about_sys.2Fcdefs.h
-
-Keep the compiler attribute definition.
-
-Remove also from noinst_HEADERS.
