modprobe has --show-modversions switch, which dumps symbols with
their modversion crcs from the __versions sections.
At the moment the section contains information for the dependency
symbols only, while exported symbols add to symtab entries with
__crc_ prefix (the format may differ, see 1e48901166 libkmod-elf:
resolve CRC if module is built with MODULE_REL_CRCS).
The patch makes it to show exported symbols as well.
The function is basically cut'n'paste of show_modversions(),
but 'version' family replaced with 'symbol' one.
