/bin/bash is not available on every system, nor always the default.
/bin/sh is standardised, but not always the preferred interactive shell,
hence it's configurable.
There's no need to check for the existence of this shell during config,
since it's an option that only affects run-time - and you may compile
ncdu on a totally different system than you would run it on.
Key 'b' in the browse window spawns a shell in the current directoy.
We first check the $SHELL environment variable of the user for the preferred
shell interpreter. If it's not set, we fall back to the compile time
configured default shell (usually /bin/bash).

Ncurses provides a pkg-config module which could be used here. If not
available we fall back to the old detection heuristic.
