modutils: remove special handling of uClibc

Commit 3a45b87ac36f (modutils: support finit_module syscall) introduced
macro finit_module. But it is not defined for uClibc.

With uClibc, we get following build errors:

  modutils.c:(.text.bb_init_module+0xa0): undefined reference to `finit_module'

uClibc wrappers.

module syscall wrappers.

Fix dependency for IFUPDOWN_UDHCPC_CMD_OPTIONS

Commit a8c696bf09d8151323f6e99348c4bc8989f829c8 makes ifup and ifdown
individually selectable, but forgets to update the dependency to
IFUPDOWN_UDHCPC_CMD_OPTIONS, so it is not selectable anymore.

This patch fixes the dependency by checking for IFUP or IFDOWN, instead
of the obsolete IFUPDOWN.

Also, it drops dependency on UDHCPC: udhcpc on the target system

libiproute: handle table ids larger than 255

Linux kernel, starting from 2.6.19 allows ip table ids to have 32-bit values.
In order to preserve compatibility, the old 8-bit field: rtm_table is still
in use when table id is lower than 256.

Add support for the 32-bit table id (RTA_TABLE attribute) in:
- ip route print
- ip route modify
- ip rule print
- ip rule modify

Add printing of table ids to ip route.

Changes are compatible with the mainline iproute2 utilities.

These changes are required for compatibility with ConnMan, which by default
uses table ids greater than 255.
