keychain: set SHELL correctly in bash and zsh
bash and zsh apparently handle command substitution slightly differently
than fish. in bash/zsh:

$ export FOO=x
$ FOO=y echo $(sh -c 'echo $FOO')
x

whereas in fish:

$ export FOO=x
$ FOO=y echo $(sh -c 'echo $FOO')
y

so we have to assign $SHELL within the substitution for bash and zsh.
