Bug#856051: more verbose output for checkbashisms (devscripts)

[Dmitriy Getman]

package: devscripts
version: 2.17.1
I added more verbose output for script checkbashisms:
possible bashism in ../bash/saymyname line 45 ($MACHTYPE should be "$(gcc
-dumpmachine"):

possible bashism in ../bash/saymyname line 188 ($HOSTNAME should be
"$(uname -n)"):
Also this script should show bashisms regardless if it dash or bash script
or regular file like /etc/profile

checkbashisms.pl
