Add support for writing compressed captures on the fly (gzip and LZ4, as supported for compressing while writing elsewhere) through writecap, by linking in file_wrappers statically. Remove the "compress a multiple file (but not ringbuffer) capture at file rotation time" option in preference to this. Fix #9311. Fix #19159
