test-merge-tools: stabilize for Windows

This masks the Windows argument parsing insanity[1], so it needs a bit of
explanation.  (The security reference in the footnote is probably useful to keep
in mind if we ever whitelist certain in-repo config settings.)

9037c29e9f53 introduced tests that were failing on Windows with an unbalanced
double quote[2].  What ends up happening here is util.shellquote() is double
quoting the file path, but the shell script is placing this ->": "<- right next
to it.  So cmd.exe gets launched with 'lb:base": ""c:\...\f~base.xyz"', which
got interpreted as 'lb:base: "c:\...\f~base.xyz'. If the test is adjusted to
quote like "lb:$labelbase: $base", then MSYS runs interference and strips the
'\' characters.  I was able to get the expected result by dropping the quotes
from '": "', and changing the space to underscore.  But since we need to glob
away the C: part anyway, just glob away the quote and leave the test unchanged.
