* Update of Flecsi Spackage
Update of flecsi spackage to reconcile differences between flecsi@1:1.9
and flecsi@2: for future support purposes
* Removing Unnecessary Conditional
Removing unused conditional. Initially the plan was to switch based on
version in `cmake_args` but this was not necessary as build system
variable names remained mostly the same and conflicts prevent the rest.
For the most part, if a variant is there it does not need to check
against what version of the code is being built.
* Updated CI To Reconcile Flecsi Changes
Updated CI to target flecsi@1.4.2 which best matches the previous
release version and reconciled change in variant name
