bitbake: tests/fetch: Make test_npm_premirrors work with the current fetcher

There are two totally opposite use cases for how a premirror is
expected to behave in combination with specifying a downloadfilename=
parameter in the SRC_URI. On the one hand there is the expectation
that it works like any other mirror, which means the premirror is
expected to contain a file with the original name specified in the
SRC_URI. On the other hand there is the expectation that one can use
the artefacts downloaded by bitbake in ${DL_DIR} as a premirror, in
which case it is expected to contain a file with the name from the
downloadfilename= parameter.

The latter case has been how downloaded files have been handled until
commit 8a3ff9f3 (fetch2: fix premirror URI when downloadfilename
defined), where the fetcher was changed to store files as per the
first case. This is also when the test_npm_premirrors test case was
modified in commit 5ba191a0 (tests/fetch: add and fix npm tests) to
expect the first case.

The above change was later reverted in commit 96c30007 (fetch2: fix
downloadfilename issue with premirror). However the
test_npm_premirrors test case was not updated to match, and has been
failing ever since. This has probably gone unnoticed because the npm
related test cases require that npm is installed on the host.

This commit updates test_npm_premirrors to expect that premirrors use
the filenames specified by downloadfilename= as this matches the
current fetcher implementation and also is the most likely use case
for premirrors. It also tries to mimic how one typically might setup
the premirror directory by simply copying the download directory.
