wget: fix update to 1.19.2 for buildbot

I modifed the commit in this PR to reflect the already pushed version bump change by @tripolar
Several targets have already failed in buildbot like
```
target-arm_cortex-a15+neon-vfpv4_musl_eabi/wget-nossl/wget-1.19.2'
Package wget-nossl is missing dependencies for the following libraries:
libunistring.so.2
```

So, let's try to overcome that libunistring linkage with a hack that makes the actual libunistring overlooked.
