pgsql: ssl: Skip passphrase reload tests in EXEC_BACKEND builds

ssl: Skip passphrase reload tests in EXEC_BACKEND builds

SSL password command reloading must be enabled on Windows and in
EXEC_BACKEND builds due to them always reloading the context. The
new tests in commit 4f433025 skipped under Windows but missed the
EXEC_BACKEND check.  Reported by buildfarm member culicidae.
