Support different PATH setting

When fsadm is test - it needs to execute lvm and fsadm from non-standard path
setting.   So adding a support in fsadm script when user set LVM_BINARY, then
the lvm command invoced from fsadm will have the same PATH setting as before
entering  fsadm command.

Needed for testing.
