[PATCH v2 2/2] t9811: replace 'test -f' and '! test -f' with 'test_path_*'

[Marcelo Machado Lage <marcelomlage@usp.br>]

Replace the basic shell commands 'test -f', with more modern test
helpers 'test_path_is_file' and 'test_path_is_missing'.
These modern helpers emit useful information when the corresponding
tests fail, unlike 'test -f' and '! test -f'.

The occurrences of '! test -f filename' were replaced by
'file_path_is_missing filename', a stronger guarantee equivalent to
'! test -e filename'.
