[no-ci] Revert "WIP: mingw_stat(): handle symbolic links that point to directories"

This reverts commit 9b550e7 and
reintroduces the breakage in t0060.221:

[...]
++ chmod +x '/usr/src/git/t/trash directory.t0060-path-utils/bin/git-test-home'
++ echo 'echo mingw64'
++ write_script pretendmingw64/bin/git-test-bin
++ echo '#!/bin/sh'
++ cat
++ chmod +x pretendmingw64/bin/git-test-bin
++ echo 'echo usr'
++ write_script pretend/usr/bin/git-test-bin2
++ echo '#!/bin/sh'
++ cat
++ chmod +x pretend/usr/bin/git-test-bin2
++ MSYSTEM=
++ GIT_EXEC_PATH=
++ pretendmingw64/libexec/git-core/git.exe test-home
++ pretendmingw64/libexec/git-core/git.exe test-bin
git: 'test-bin' is not a git command. See 'git --help'.
error: last command exited with $?=1
not ok 221 - MSYSTEM/PATH is adjusted if necessary
