[#25499]yugabyted: Fix the failing test org.yb.yugabyted.TestYugabytedPgParity#testPgParity

Summary:
`org.yb.yugabyted.TestYugabytedPgParity#testPgParity` Test started failing in the [[ e1d5952 | commit ]]

Since the coredb itself adds `local all yugabyte trust` to `ysql_hba_conf`, removing the code in yugabyted to add it.
Jira: DB-14758

Test Plan: ./yb_build.sh --java-test 'org.yb.yugabyted.*'
