[Rpm-maint] [rpm-software-management/rpm] Support new %[ ] expression expansion syntax (#846)

[Michael Schroeder]

Ah, I get what you mean. I think we should print a bare word error if the expanded string does not start with a digit. This makes it similar to what `%{expr:...}` and `%if` does:
```
$ ./rpm --define "aaa a" --define "bbb 123b" --eval '%{expr: %aaa }'
error: bare words are no longer supported, please use "...":  a 
error:                                                        ^
$ ./rpm --define "aaa a" --define "bbb 123b" --eval '%[ %aaa ]'
error: macro expansion returned a bare word, please use "...":  %aaa 
error:                                                          ^
error: expanded string: a
$ ./rpm --define "aaa a" --define "bbb 123b" --eval '%[ %bbb ]'
error: macro expansion did not return an integer:  %bbb 
error:                                             ^
error: expanded string: 123b
```
