modpost: fix unwanted VMLINUX_SYMBOL_STR expansion
Commit a4b6a77b77ba4f526392612c2365797fab956014 ("module: fix symbol
versioning with symbol prefixes") broke the MODVERSIONS loading of any
module using memcmp (e.g. ipv6) on x86_32, as it's defined to
__builtin_memcmp which is expanded by VMLINUX_SYMBOL_STR. Use
__VMLINUX_SYMBOL_STR instead which doesn't expand the argument.
