[Buildroot] [git commit branch/2022.02.x] package/ipmiutil: fix uclibc build without wchar

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=755cdb0fe48ba1fb3a5f222f68732d43bbe72117
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.02.x

For an unknown reason, wchar_t is incorrectly detected with uclibc
resulting in the following build failure:

In file included from igetevent.c:136:
imb_api.h:150:5: error: unknown type name 'wchar_t'
  150 |     wchar_t *Buffer;
      |     ^~~~~~~

The build failure can be reproduced even when reverting bump to version
3.1.8.
