Hi all,

A bash in a local mounted drive, use realpath instead of mounted one
for all child processes.

Example, mount a local folder on Z: drive, go in there and run any
external command:
$ subst Z: C:\\Users
$ cd /cygdrive/z/
$ /bin/pwd
/cygdrive/c/Users

Expected
/cygdrive/w

Issue since Cygwin 3.3 and also with latest snapshot (2022-02-17
