hurd: unbreak build on GNU/Hurd (#3450)

The GNU/Hurd platform does not define IP_ADD_SOURCE_MEMBERSHIP,
IP_DROP_SOURCE_MEMBERSHIP, MCAST_JOIN_SOURCE_GROUP and
MCAST_LEAVE_SOURCE_GROUP.

Implement a few functions for the GNU/Hurd. Specifically:

* uv_resident_set_memory (from Linux)
* uv_get_free_memory (from Linux)
* uv_get_total_memory (from Linux)
* uv_cpu_info (from cygwin)
* uv__process_title_cleanup (void)
* uv_get_constrained_memory (stub)
* Leave proctitle unimplemented on Hurd for now
* Implement hurdish uv_exepath
* Enable ifaddrs api
* Unbreak udp basics
* Unbreak futime and lutime on Hurd

cygwin: implement support for cygwin and msys2

Cygwin and MSYS2 are POSIX layers implemented on top of Windows.
Use our POSIX `poll(2)` implementation of our poll abstraction.
For most other components we already have dedicated sources
implementing them in terms of APIs available on Cygwin or
providing non-implementations of components not supported.

This leaves only three components that need Cygwin-specific
implementations:

* uv_uptime: implement using sysinfo
* uv_resident_set_memory: add a placeholder returning UV_ENOSYS
* uv_cpu_info: add a placeholder returning UV_ENOSYS

Update our test suite to account for features not available
due to Cygwin platform limitations or our placeholders.
