doc/fast-import: document feature import-marks-if-exists 

fast-import command-line option --import-marks-if-exists was introduced
in commit dded4f1 (fast-import: Introduce --import-marks-if-exists, 2011-01-15)

--import-marks option can be set via a "feature" command in a fast-import
stream and --import-marks-if-exists had support for such specification
from the very beginning too due to some shared codebase. Though the
documentation for this feature wasn't written in dded4f1.

Add the documentation for "feature import-marks-if-exists=<file>". Also add
a minimalistic test for it.

Like --import-marks except in two respects: first, only one
"feature import-marks" command is allowed per stream;
second, an --import-marks= command-line option overrides
any "feature import-marks" command in the stream.
"feature import-marks" or "feature import-marks-if-exists"
command is allowed per stream; second, an --import-marks=
or --import-marks-if-exists command-line option overrides
any of these "feature" commands in the stream; third,
"feature import-marks-if-exists" like a corresponding
command-line option silently skips a nonexistent file.
