MDEV-30765 SHOW TABLES not working properly with lower_case_table_names=2

Browse Source 
lower_case_table_names=2 means "table names and database names are
stored as declared, but they are compared in lowercase".
But names of objects in grants are stored in lowercase for any value
of lower_case_table_names. This caused an error when checking grants
for objects containing uppercase letters since table_hash_search()
didn't take into account lower_case_table_names value
