fix(examples): simple http_server example build for Linux target

Browse Source 
Static task creation on Linux target had issues with insufficient stack
memory allocation. Type of `StackType_t` is `unsigned long` and hence
it must be considered during stack memory allocation.

Fix ensures proper working of simple HTTP server example.
