[flang-rt] Enable lit internal shell by default (#156095)

This patch enables the lit internal shell by default for testing
flang-rt. The lit internal shell is able to run tests a bit faster as it
avoids having to fork bash for every run line and also produces nicer
debug information on failures.

This is part of #102704.
