[Buildroot] [PATCH] package/ipmitool: fix patch

[Heiko Thiery <heiko.thiery@gmail.com>]

The previous commit to this package
(37c5e903a7e18f5b3847c11a40af5f74984d6c77) introduced a bunch of patches
to fix a CVE. Unfortunatly only applying of the patches was tested but
not building the package.

This commit replaces a define that was introduced in a previous patch
upstream and caused the build failure.

Tested:

                             br-arm-full [1/6]: OK
                  br-arm-cortex-a9-glibc [2/6]: OK
                   br-arm-cortex-m4-full [3/6]: SKIPPED
                          br-x86-64-musl [4/6]: OK
                      br-arm-full-static [5/6]: OK
                            sourcery-arm [6/6]: OK

+The patch is slightly modified manually. The define
+(MAX_CIPHER_SUITE_DATA_LEN) was introduced upstream in another patch.
+Replace the define by the value 0x10.]
