[Build]: Fix pip version constraint conflict issue (sonic-net#10525)

Why I did it
[Build]: Fix pip version constraint conflict issue
When a version is specified in the constraint file, if upgrading the version in build script, it will have conflict issue.

How I did it
If a specified version has specified in pip command line, then the version constraint will be skipped.
