Subject: [PATCH] Fix DynamicLibrary::Load unit test under Cygwin

While running the test_base on CYGWIN, this message will be printed on the console:

-------------------------------------------------------------------------------
DynamicLibrary::Load
-------------------------------------------------------------------------------
/cygdrive/c/Users/carlo/Documents/GitHub/wxWidgets/tests/misc/dynamiclib.cpp:26
...............................................................................

/cygdrive/c/Users/carlo/Documents/GitHub/wxWidgets/tests/misc/dynamiclib.cpp:80: warning:
  Couldn't find libc.so, skipping DynamicLibrary::Load() test.

/cygdrive/c/Users/carlo/Documents/GitHub/wxWidgets/tests/misc/dynamiclib.cpp:84: warning:
  Possible candidates:
  /lib/libc.a
  /usr/lib/libc.a

CYGWIN uses NEWLIB as C library and it is compiled into cygwin1.dll.
This patch adds the right test case for CYGWIN, for letting the execution of the test.

See #23781.

(cherry picked from commit 1bc8631b527603c855d65a9ede45fa3d6e672ea8)
