Note that it is impossible to hide injecting trace of virtual memory maps from the hooked target process.
ReZygisk will only focus on removing its trace for approcess that are not hooked by modules.
1. fix typo vsdo -> vdso and allow this symbol to be not found, which is the case for the 32bit linkers on some devices
2. use soinfo_free to fully remove the soinfo record of libzygisk.so
3. set `soinfo.size = 0` to avoid the library being unmapped while removing its soinfo record
4. add more debug logs for troubleshooting
In Bionic linker, the `soinfo` structure has a field `next`, which points to the next loaded library in a linked list consisting of all loaded libraries.
Hence, an injected process can easily find all loaded libraries.
Previously in ReZygisk, module library records are hidden by setting the `pathname` field to be empty, which is futile but easier to detect.
Current idea of dropping record can be found in the following commit:

On Android 15+ in some devices, the symbol names of some static variables such as `solist`, has a `llvm` suffix in its exported name.
Current commit handles this case and close#63 as fixed.
