Fix compilation errors on MinGW (#3217)

Before PR compilation failed because of two errors:

1 - Usage of CMake target_link_libraries()

Make Error at CMakeLists.txt:154 (target_link_libraries):
  The keyword signature for target_link_libraries has already been used with
  the target "iwasm_shared".  All uses of target_link_libraries with a target
  must be either all-keyword or all-plain.

  The uses of the keyword signature are here:

   * CMakeLists.txt:148 (target_link_libraries)

See https://stackoverflow.com/questions/47737558/uses-of-target-link-libraries-must-be-either-all-keyword-or-all-plain

Fixed by adding keyword INTERFACE

2 - Undefined symbols during linkage, fixed by adding -lwsock32.
