[PING^3 PATCH 1/1] sim/testsuite: Trim extra path from arch

[Tsukasa OI <research_trasio@irq.a4lg.com>]

If subdir begins with "./", sim_arch returned "./ARCH" instead of
"ARCH" and target-specific check-sim is prevented.  This commit fixes
the issue to make "make check-sim" work.

sim/ChangeLog:

	* testsuite/lib/sim-defs.exp: Fix return value of sim_arch
	by trimming leading "./".
