[gdb/testsuite] Split up multi-exec test-cases

With test-case gdb.base/align.exp and target board native-gdbserver, we run
into:
...
(gdb) file outputs/gdb.base/align/c/align^M
Reading symbols from outputs/gdb.base/align/c/align...^M
(gdb) delete breakpoints^M
(gdb) info breakpoints^M
No breakpoints or watchpoints.^M
(gdb) break main^M
Breakpoint 1 at 0x4004ab: file outputs/gdb.base/align/c/align.c, line 838.^M
(gdb) kill^M
The program is not being run.^M
(gdb) spawn gdbserver --once localhost:2592 outputs/gdb.base/align/align^M
Process outputs/gdb.base/align/align created; pid = 6946^M
Listening on port 2592^M
target remote localhost:2592^M
Remote debugging using localhost:2592^M
warning: Mismatch between current exec-file outputs/gdb.base/align/c/align^M
and automatically determined exec-file outputs/gdb.base/align/align^M
exec-file-mismatch handling is currently "ask"^M
Load new symbol table from "outputs/gdb.base/align/align"? (y or n) Quit^M
(gdb) ERROR: test suppressed
...

Fix this by turning this and similar test-cases into regular, single
executable test-cases.

This fixes 100+ FAILs with target board native-gdbserver.

Tested on x86_64-linux.
