[LTP] [PATCH V7 17/19] syscalls/utimensat: Migrate to new test framework

Viresh Kumar
2020-06-26T06:22:30Z

This gets rid of the test script and updates the utimensat01.c file to
handle most of the tests covered earlier (apart from testing the same
for files owned by root, as the test is run as root right now).
