postgresql: remove *_config from SSTATE_SCAN_FILES
postgresql: remove *_config from SSTATE_SCAN_FILES

It fails to run command pg_config with segment fault. The root cause is
function sstate_hardcode_path takes elf file pg_config as a configure
file and edits it with 'sed'.

And then file pg_config is corrupt:
$ readelf -a package/usr/bin/pg_config >/dev/null
readelf: Error: Unable to read in 0x700 bytes of section headers
readelf: Error: Section headers are not available!

There is not other '*_config' file installed by postgresql except
pg_config, so remove '*_config' from SSTATE_SCAN_FILES for postgresql.
