Fix unintentional behavior change in commit e9931bfb75.
Prior to that commit, there was special case to use ASCII case mapping behavior for the libc provider with a single-byte encoding when that's the default collation. Commit e9931bfb75 mistakenly eliminated that special case; this commit restores it. Discussion: https://postgr.es/m/01a104f0d2179d756261e90d96fd65c36ad6fcf0.camel@j-davis.com
