build system: drop PLATFORM_LINUX
...
PLATFORM_LINUX is a hidden configuration option which is disabled by
default and enabled at over a hundred locations for features that are
deemed to be Linux specific.
The only effect of PLATFORM_LINUX is to control compilation of
libbb/match_fstype.c. This file is only needed by mount and umount.
Remove all references to PLATFORM_LINUX and compile match_fstype.c
if mount or umount is enabled.

This merges the in-memory module info structures of modprobe
and depmod. This allows sharing hashing by modulename code
improving depmod runtime with almost factor of 2x.

- a lot faster (linear algorithmic complexity, smaller memory foot print)
- a lot smaller (the old code was overly complicated)
- loading of aliases is now module-init-tools compliant
- blacklisting is done correctly (-b option added)
- module argument quoting done right
- depmod now correctly generates modules.symbols and modules.alias

We would try to be clever and compare the *data instead of the *elt.
Somethink like this might be of more general use:
/* Unlink arbitrary element from the list that contains data */
void llist_unlink_data(llist_t **head, void *data)
{
llist_t *elt;
for (elt = *head; elt; elt = elt->link) {
if (elt->data == data) {
llist_unlink(elt);
return;
}
