Hot fix for libgomp vendoring

[hcho3]

Closes #6480
Closes #6481

#6461 caused segfault on CentOS and Debian platforms upon running import xgboost because the shared library libxgboost.so was not properly patched by auditwheel repair. According to pypa/auditwheel#227 (comment), the patchelf program in CentOS 6 or 7 is outdated and contains bugs that leads to rending libxgboost.so unreadable on CentOS / Debian.

Error log:

Inconsistency detected by ld.so: dl-version.c: 205: _dl_check_map_versions: Assertion `needed != NULL' failed!

Solution. Use the official container from PyPA, manylinux2010_x86_64, to run auditwheel repair command. This will use the latest patchelf program and thus patch libxgboost.so correctly. This container is "blessed" by the Python Packaging Authority (PyPA) and is able to produce wheels that are strictly compliant with the "manylinux" standard.

Note. The issue is quite serious, so I'll publish a new Python wheel with version 1.3.0.post0. I will pull down the current version 1.3.0 to prevent others from running into the issue.

Note. The ARM64 wheel is not affected by this bug, because it was produced by the official container manylinux2014_aarch64.

The 1.3.0.post0 version is now available on PyPI: https://pypi.org/project/xgboost/1.3.0.post0/#files
