[dev.unified] test: relax issue7921.go diagnostic message

Browse Source 
For constants literal, iimport/iexport read/write them as basic literal
nodes. So they are printed in diagnostic message as Go syntax. So "foo"
will be reported as string("foo").

Unified IR read/write the raw expression as string value, and when
printed in diagnostic, the string value is written out exactly as-is, so
"foo" will be written as "foo".

Thus, this CL relax the test in issue7921.go to match the string value only.

Updates #53058
