Duplicated shorthand argument in latest release "-M"

[nmollerup]

PR #36 introduced a redefinition of the shorthand argument "M".

sensu-check-log/main.go

Line 242 in 025215c

Shorthand: "M",

But that was already defined here:

sensu-check-log/main.go

Line 175 in 025215c

Shorthand: "M",

This results in a panic:

panic: unable to redefine 'M' shorthand in "sensu-check-log" flagset: it's already used for "missing-ok" flag
