PR ld/20828: Remove leading `_' from symbols used in tests

Complement commit 81ff47b3a546 ("PR ld/20828: Fix linker script symbols
wrongly forced local with section GC") and remove the leading underscore
from `_fdata' and `_edata' symbols used in tests, fixing a:

FAIL: PR ld/20828 dynamic symbols with section GC (version script)

failure with targets such as: `bfin-elf', `bfin-uclinux', `metag-elf',
`metag-linux' `mn10300-elf', `sh-elf', `sh64-elf', and possibly other
ones, that have `_' set (with `elf_symbol_leading_char') as the leading
character for symbols.  As from commit 93252b1cf41a ("bfd/ld: handle ABI
prefixes in version scripts") these targets strip the leading underscore
before applying version script rules, because the (default) syntax for
symbol names is that of the C language rather than their low-level
symbol table encoding.
