[Buildroot] [git commit branch/2020.08.x] package/xerces: fix typo, which re-enables package

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=ef2ce170c6e53538c65a9893d8b000f6b7ddd3e4
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.08.x

Commit 4e60247be67a8e7f9937a8bf2b123ddb2be9dad2 ("package/xerces: fix
coding style in Config.in") introduced a silly typo in the xerces
package depends on... which effectively made it impossible to enable
this package as the "USE_WCHAR" option does not exist.
