Subject: [PATCH] winpr/library: Use RTLD_GLOBAL for dlopen

LoadLibraryA implementation uses the RTLD_LOCAL flag for dlopen currently.

This flag doesn't allow the symbols to be used by the subsequently loaded

libraries. This is a problem for the video channel when -DBUILTIN_CHANNELS=OFF

is used as it uses functions from the geometry channel. Let's use RTLD_GLOBAL

instead to prevent "undefined symbol" errors in such cases.

Fixes: https://github.com/FreeRDP/FreeRDP/issues/6236
