Reformat shell scripts with shfmt 
All changes in this commit were automated using the command:

shfmt -w -i 2 -ci -bn . $(find . -name "*.sh.in")

By default, only *.sh and files without extension are checked, so
*.sh.in files have to be added additionally. (See mvdan/sh#944)

The rsabigexponent test is used to check max-rsa-exponent-size.

We only run this test on builds without PKCS#11, as we have control over the RSA exponent size with plain OpenSSL. We have not explored how to do this with PKCS#11, which would require generating such a key and then signing a zone with it. Additionally, even with control of the exponent size with PKCS#11, generating a DNSKEY with this property and signing such a zone would be slow and undesirable for each test run; instead, we use a pregenerated DNSKEY and a saved signed zone. These are located in rsabigexponent/ns2 and currently use RSASHA1 for the DNSKEY algorithm; however, that may need to be changed in the future.

To generate the DNSKEY used in this test, we used bigkey.c, as dnssec-keygen is not capable of generating such keys.

Do not remove bigkey.c as it may be needed to generate a new DNSKEY for testing purposes.

bigkey is used to both test that we are not running under PKCS#11 and generate a DNSKEY key with a large RSA exponent.

To regenerate ns2/example.db.bad comment out the range test in opensslrsa_parse before signing the zone with a ZSK key generated by bigkey.
