Rich Felker d9179b4aa4 sh: fix debug trap failure to process signals before return to user
[ Upstream commit 96a598996f ]

When responding to a debug trap (breakpoint) in userspace, the
kernel's trap handler raised SIGTRAP but returned from the trap via a
code path that ignored pending signals, resulting in an infinite loop
re-executing the trapping instruction.
