Installed shell scripts need +X permissions.

[KineticTheory]

Background

• I'm still working out all of the kinks related to switching from BullseyeCoverage to gcov/lcov coverage reporting. I am hopeful this fixes the the last remaining issue. The helper script capture_lcov.sh did not have execute permission when installed.

Purpose of Pull Request

• Related to Redmine Issue #1930

Description of changes

• When installing shell scripts use install( PROGRAMS ... ) instead of install(FILES ... ).
