Ensure absolute path for include

Ensure the path of file to include in `instance_t::include_directive`
is always an absolute path.

Previously when the journal file is given through stdin, we prepend a
"./" to the filename to include. However, in Boost >= 1.77,
`path::normalize` strips the leading "./" [1]. Our `resolve_path`
function calls `normalize` and thus now it returns "file" for "./file"
instead of the previous "./file".

This change causes a failing test regress/BF3C1F82-2 [2], and also
breaks the `include` directive for stdin input:

    $ touch file-to-include
    $ echo "include file-to-include" | ledger -f - reg

gives

    While parsing file "", line 1:
    Error: File to include was not found: "file-to-include"

Therefore, we change to prepend the `context.current_directory` to
make the filename absolute in this case as well. The test
regress/BF3C1F82-2 is also updated to match the new output.

Fixes #2075.
