[Buildroot] [git commit branch/next] package/tpm2-tools: disable on uClibc, due to c16rtomb()

[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=3d63951ab897ae789be863ada148d0e9ee6f54e6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Since upstream commit eca77c1419617a8e2d6d8008bac716878b0c27ca, the
c16rtomb() wide-char function is used by tpm2-tools, but this function
is not implemented by uClibc.

This commit first appeared in tpm-tools 4.2, and therefore the bump
from version 4.1.2 to 4.3.2 in commit
91aa6efa8588bf7617cc4a640eb55052b524ceb7 causes a build failure on
uClibc configurations.

An issue was reported at
https://github.55860.com/tpm2-software/tpm2-tools/issues/2785, but in
the mean time, we disable tpm2-tools on uClibc configurations.

Fixes:
