treemanifest: stop storing full path for each item in manifest._lazydirs

This information is obtainable, if needed, based on the lazydirs key (which is
the entry name) and the manifest's `dir()` method.

### Performance

This is actually both a memory and a performance improvement, but it's likely to
be a very small one in most situations. In the pathological repo I've been using
for testing other performance work I've done recently, this reduced the time for
a rebase operation (rebasing two commits across a public-phase change that
touches a sibling of one of my tracked directories where the common parent is
massive (>>10k entries)):

#if gettext

Test translated help message

str.lower() instead of encoding.lower(str) on translated message might
make message meaningless, because some encoding uses 0x41(A) - 0x5a(Z)
as the second or later byte of multi-byte character.

For example, "\x8bL\x98^" (translation of "record" in ja_JP.cp932)
contains 0x4c (L). str.lower() replaces 0x4c(L) by 0x6c(l) and this
replacement makes message meaningless.

This tests that translated help message is lower()-ed correctly.
