This commit also modifies how driver.makefile processes .st/.stt files.
According to the SNL documentation, .stt files should not be pre-processed.
However, driver.makefile has historically been performing the exact same
actions to both types of files, counter to what the documentation said.

Ensure that EPICS_DRIVER_PATH is set first

See merge request e3/e3-require!101

Previously, it was the case that running
```
$ iocsh -r module -l cellMods
$ iocsh -l cellMods -r module
```
would both work correctly, but if you looked at the IOC log it was not
clear why that was the case; in the former case it _appeared_ like we
were finding the module before setting `EPICS_DRIVER_PATH`. This only
worked because this variable is exported from the shell.

This change forces the `-l` flag to be processed _before_ all of the
other flags in order to ensure that paths are determined first.
