quotearg: avoid uninitialized variable use

Coverity correctly deduced:

Error: UNINIT:

m4-1.4.16/lib/quotearg.c:175: uninit_use: Using uninitialized value "o": field "o".right_quote is uninitialized.

When custom_quoting_style was introduced in commit 12247f77,
this method was not updated, and any caller that passed
the new enum value to any of the existing quotearg_*style

That was already documented as unspecified behavior, though,
so changing to an abort makes it easier to spot bad code that
passes the wrong enum value, rather than waiting for the
eventual bad memory dereference later on.

Most callers of quotearg_*style were using quoting_style_args
and quoting_style_vals to map strings to particular enum
values, and custom_quoting_style is (intentionally) not covered
