block/curl: Replace usleep by g_usleep

The function usleep is not available for all supported platforms:
at least some versions of MinGW don't support it.

usleep was also declared obsolete by POSIX.1-2001.

The function g_usleep is part of glib2.0, so it is available for
all supported platforms.

Using nanosleep would also be possible but needs more code.
