package/sconeserver: bump version to fix musl build

Fixes this musl build error:
TermBuffer.cpp: In member function ‘virtual scx::Condition scx::TermBuffer::read(void*, int, int&)’:
TermBuffer.cpp:83:10: error: ‘CEOT’ was not declared in this scope
     case CEOT:
          ^
TermBuffer.cpp:123:10: error: ‘CERASE’ was not declared in this scope
     case CERASE: // Backspace
          ^
The autobuilders did not catch this specific error yet because they
failed earlier with other packages, but I am continuing the build based
on the defconfig from:
http://autobuild.buildroot.net/results/6cc/6cc0f8c067e07deea688b9b97284601a596b898c/

- added hash
- removed 0001-fix-ssl-libs-ordering.patch, applied upstream:
  https://github.com/sconemad/sconeserver/commit/ffb69ca18fd03d0dc976696144d215b3a8555155
- disabled markdown module because its git submodule cmark
  ( https://github.com/sconemad/sconeserver/tree/master/markdown

 )
  has no cross-compile support provided by the sconeserver build system:
