[PATCH v3 16/28] t55[4-9]*: adjust the references to the default branch name "main"

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

This trick was performed via

	$ (cd t &&
	   sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \
		-e 's/Master/Main/g' -e 's/retsam/niam/g' \
		-- t55[4-9]*.sh t556x*)

This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main`
for those tests.

Note that t5541 uses the reversed `master` name: `retsam`. We replace it
by the equivalent for `main`: `niam`.
