[PATCH v2 1/3] [gdb] Re-indent regformats/regdat.sh

[Tom de Vries <tdevries@suse.de>]

The script gdb/regformats/regdat.sh has inconsistent indentation: both 2 and 4
spaces.

Standardize to 4 spaces (as specified by .editorconfig), and document this
explicitly using a Local Variables setting, copied from
gdb/contrib/expect-read1.sh.
