overlay: do not set OVL_BASE_FSTYP value to "overlay"

Browse Source 
The purpose of OVL_BASE_FSTYP is to store the value of FSTYP that is
found in a host config file section.

When there is no host config file or if user sets FSTYP=overlay in config
file, it makes no sense to store the value "overlay" in OVL_BASE_FSTYP
and it is better to leave it empty or leave its current value in tact.

This allows user to set OVL_BASE_FSTYP in config file or before running
the test to support queries about base fs, such as
_require_metadata_journaling, even when running an overlay test.
