  [PowerPC][clang] Fix triple constructor ambiguity causing "unknown" target triple on AIX (#147488)

PR #145685 introduced constructor overload ambiguity in the Triple
class, causing `updateTripleOSVersion()` to construct Triple objects
with `unknown` instead of the configured target triple (e.g.,
`powerpc-ibm-aix7.3.0.0`). This results in Clang driver errors like
`error: unknown target triple 'unknown'`.

Used `Twine` constructor with braced initialization to bypass ambiguity.
