test: fix t7001 cp to use POSIX options

Since 11502468 and 04c1ee57 (both first appearing in v1.8.5), the
t7001-mv test has used "cp -a" to perform a copy in several of the
tests.

However, the "-a" option is not required for a POSIX cp utility and
some platforms' cp utilities do not support it.

The POSIX equivalent of -a is -R -P -p.

Change "cp -a" to "cp -R -P -p" so that the t7001-mv test works
on systems with a cp utility that only implements the POSIX
required set of options and not the "-a" option.
