[LTP] [PATCHv2] syscalls/quotactl04: add mkfs.ext4 package version check

The project quota feature was added in e2fsprogs 1.43 [1]:
E2fsprogs 1.43 (May 17, 2016)
Add support for the ext4 metadata checksum, checksum seed, inline
data, encryption, project quota, and read-only features.
The test should be skipped when running with older package, otherwise
it will fail with:
Invalid filesystem option set: quota,project
Use popen and fscanf to get mkfs.ext4 -V output for version
comparison. This version checking by adding digits together does not
work with alphabets in the number like rc1, but in that case the test
will still be tested.
It will now be skipped with (Tested with Ubuntu Xenial + 4.15 kernel):
quotactl04.c:118: TCONF: Test needs mkfs.ext4 >= 1.43 for encrypt
option, test skipped
