[Rpm-maint] [rpm-software-management/rpm] Revere Change %undefine macro to "func" style now that we can (PR #2203)

[xujing]

> Some obscure corner-cases changing behavior is kinda expected in this kind of cleanup. Is there some real-world usage which breaks because of this, something that can't be trivially fixed?

Through test cases, I found that the https://github.com/rpm-software-management/rpm/commit/aec8bdb53a3013eabf16368e17a65ab69c2136ee changed the function. As a result, the behavior of some commands is changed. Currently, there is no actual service problem. I haven't had any problems with the business until now.

In addition, through code analysis, I find that the character string of undefine is determined whether the character string belongs to "a-z" or "A-Z" or "0-9" or '_'
