package/ipmitool: fix 0011-channel-Fix-buffer-overflow.patch

Browse Source 
The previous commit to this package
(37c5e903a7) 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.]
